Reliable and efficient power source: Industry the important accelerator of 4

 

4 application should realize industry the innovation requirement that taller productivity can need to satisfy the following respects: Flexible, efficiency, communication, security, dependability. And the application of all industry product cannot leave power supply. In efficient, minor volume, low EMI these 3 dimension are spent, ADI can provide very powerful support and the security that a series of innovation products will come to satisfy disparate industry to use domain power source and dependability requirement.

 

Graph 2: Synchronism of “ of index of 3 great performance realizes ADI Power By Linear“ , help strength to industry 4 transfer

 

In the industrial control system that waits for a model in control of such as motor, the EMI that inputs end, noise is very crucial to the stability of whole system, meanwhile because present systematic power comsumption also is a problem, close a road to do, the past can use diode, will tell to the application of tall electric current, use common diode to be able to have a lot of corrupt practice, ADI innovation ground rolled out ideal diode plan, work to promoted the security of whole system and efficiency to do rife.

 

Pursue for example 2 medium LTC4357 of controller of diode of tall voltage ideal is used at drive MOSFET of raceway groove of an exterior N in order to replace diode of a Xiao Te radical, can realize low-down to press difference (MOSFET is in charge of guide electrify block is very low) , great improve efficiency, can help effectively thereby reduce power comsumption, hot dissipation, tension the loss is cut PC board area (need not carbon fin) , raised dependability, enhanced systematic whole efficiency.

 

Graph 3: The program of innovation —— ideal diode that industry dominates a system to input side

 

In industrial domain, EMI is the issue that does not confuse. “ we are unthinkable the factory in robot of a big batch, because of the problem of EMI, systematic dead plane, the effect that cause is very tremendous. The reason of systematic dead plane has a lot of kinds, among them electromagnetism interference is a main reason. ”Lorry expresses.

 

Challenge to answer the power source that comes true very hard to exceed low EMI, the Silent Switcher technology of ADI is particularly right noise and interference origin undertook deepness is optimized. Realized breakthrough and innovation from the angle of project physics. It made two retrorse electric current ring on chip design, the lines of force that the biggest gain of two retrorse loop is generation closes, meet to the interference of outside EMI a lot of smaller. Be in microcosmic on, bind calm kernel no longer with golden line, use the means of outfit however area of cut annulus road, let EMI fall further lowest. Adopt a series of technology optimize, obtained first-rate EMI property, need not special optimize, the standard is designed can standard of sufficient CISPR25 Class 5 EMI.

 

Lorry citing the chip of newest generation LT8614 that uses Silent Switcher technology. It optimizes magnetic field to close through two reverse voltaic annulus paths not only method, optimize the ringing SW ascendant edge to be controlled very smally through systematic annulus road at the same time, enclose craft plus what its optimize highly, its EMI is quite low. Besides, it is great still reduced ripple, solved noise problem, the dependability the system, stability can be done very well.

 

Graph 4: Silent Switcher implementation exceeds power supply of low EMI switch

 

“Silent Switcher is past of technology of global power source a few years the biggest innovation, it is platform of a technology, metropolis of product of prospective ADI Power By Linear’ as far as possible go up toward this technology platform migratory. ”Lorry discloses, “ dominates a field in Chinese robot, industry, be in even car domain, major client is interested in Silent Switcher technology very much, because be in,go, client of almost all industry or automobile client, light is the time that the attestation problem that should solve EMI wants to pass half an year go doing rectify and reform, after passing, ability can appear on the market. The occurrence of Silent Switcher technology, helped our client save the time of large half an year. ”

 

In industrial domain, minor volume also is a way that people drives. The wide extensive that ADI gives priority to with µModule is high-powered combination of product of module of module power source brings “ of again and again to industry small the surprise that is big ” namely, and a very all ready range of products is in the power source product of ADI.

 

The density that industry designs now and the complex rate of board card are higher and higher, and the time that the stability place of the dependability of man-machine interface, control, loop, software, system spends will be increasing, how to reduce a client to design difficulty, accelerate the iteration rate of products plan, how to help a client circuit of cut power source board dimension and the complex rate that circuit designs? ADI rolls out µModule of epoch-making product of power source module before 10 years, very will complex in the past power source system is compositive in a module, the client does not need to pay close attention to the noise of power source, ripple, need to be taken simply in that way like LDO only it is OK to use, efficiency is very tall also.

   

For example, bulk of LTM4622 of manostat of ultrathin double passageway, ultrathin, 2.5A or odd 5A step-down DC/DC μModule has 6.25mmX6.25mmX1.8mm only, can offer first-rate function and output. And another taller compositive spent example is LTM4668 also be to be aimed at industrial domain, dimension is 6.25mmX6.25mm, ply has 2.1mm only. Voltage is in be based on voltaic feedback model to make control to whole annulus road, can pass a different output paralell connection to be together, can receive the combination of different electric current.

Make intelligent car a safe future

 

No matter unit to driving automatically, power source / illume of assembly of batteries management, motivation or information entertainment system, light is waited a moment, in the transitional process of domain of product of car power source, “ safe ” is a keyword from beginning to end, and in the innovation solution that offers in ADI, this may mirror what in making a speech for Lorry, mention to exceed low noise (electromagnetism is disturbed) , batteries is active and balanced optimize with energy (safety drives more Sunday run) , tall low-pressure and two-way changeover, new surge and high-pressured protection mechanism wait innovation technology character a moment.

 

Lidar, common radar, relevant measure measure charging unit is future drives automatically special core and crucial platform. Lorry says, because the precision of radar and lidar and function, stability is very important, be aimed at radar, radio frequency, high frequency applying so, ADI rolled out a few power source of global noise lowest: Be like LT3042, LT3045, noise has 0.8 small hot season only, as about the same as batteries. Be such technologies drive and develop, make ADI can is drive automatically the domain offers better performance and reliability, promote industrial development.

 

Graph 6: The ideal LDO that 77/79GHz car radar applies chooses

 

And in be aimed at car system, different voltage coexistence is in circumstance, if Lorry place introduces,the design train of thought of LTC3871 is, the vehicle with increasingly complex “ carries electronic power to increase brought electricity to increase accompanied thicker cable to provide bigger voltaic capability. The occurrence of 48V system is to optimize cable and automobile body wiring, but a lot of systems equip, still be in short-term inside do not have a law to 48V system migratory, because this comparatives for some time inside, system of meeting occurrence 48V and 12V fasten the situation with concomitant all, the batteries group join of the batteries group a 48V and 12V rises, OK and two-way power supply, undertake administrative to 48V and 12V system. Can assure the problem that runs in safety of whole car system so. ”

 

Graph 7: The two-way and polyphase synchronous step-down that in the light of 48V/12V double batteries applies / plan of step up controller

 

For this, lorry still was each media to reveal in the spot on graph a such systematic board, explain: Its changeover power has “ 2.5 kilowatt, can provide first-rate stability. This is the configuration of extraordinary level inside the car of system of new generation 48V, also can realize two-way voltage changeover. ”

 

And will tell from the security of car system and dependability, because storage battery is in with more and more complex system,the car still is met when starting or circumstance of high pressure of occurrence instant of the meeting when be disturbed accidentally, and the bad damage that this causes package probably. Traditional solution is to tote TVS pipe, but it has the drawback such as larger volume and relatively tall weight. So is ADI how solve?

 

Graph 8: The surge that can replace TVS and fuse is restrained implement plan

 

Lorry solves: “ can consider to use surge to restrain implement (Surge Stopper) series product will protect a car all sorts of function module. Total need drops the share of aiguille of interference power source that controls an instantaneous pulse through feedback annulus road and MOSFET, ensure output voltage is in the standard limits of our set, system of automobile body system will be more safe. The power source craft that recombine can accuse, automobile body system won’t cause package damage because of accident interference. ”

 

The power comsumption of tall chip of high power density that straight face 5G corresponds is challenged

Well-known, arrive from 2G, 3G, 4G 5G, no matter be radio frequency parts of an apparatus or power source parts of an apparatus, what there is ADI inside the iteration of system of every time communication is heavy degree participate in.

 

The 5G communication system of instantly needs very high power density; Accordingly, the power comsumption of chip and changeover efficiency are faced with bigger adjustment. Lorry says: The DC/DC power source of “ tradition, because the switch loss of MOSFET and inductance change the existence of loss, efficiency gains revolutionary headway below current structural frame without method, ADI is ongoing the transformer LTC7820 that sent a kind to do not have inductance, can promote efficiency 99% tall. But because typical job principle is, input voltage 50% discount step-down alternates, cannot adjust output voltage, because this ADI developed to mix again model LTC7821 of switch power source, do not have inductance integratedly the advantage of efficient transformer and high-powered step-down circuit, try other technology and principle application, while output voltage can be adjusted at will, still carry efficiency in 97% above. ”

 

Graph 9: Can go up in the area of stamp size without LTC7820 of converter of inductance bus line the efficiency that achieves 97% above

 

ADI innovates in the power source technology of communication application and adjust a respect to return those who did a lot of other to improve. The advantage support heat that combines ideal diode for instance is inserted unplug, can let communication system gain better than before stability. And the power source condition that can record each through taking the system of power source management of digital interface, voltage, electric current, temperature, can control the voltage of output even. Do not stabilize when the system especially when, can be informed circuit breakdown place through PSM. Accordingly, the adjustment of the measurement of PSM and output the function is corresponding domain more and more get put sb in a very important position.

 

Graph 10: The power source supervisory system that takes digital interface (PSM)

 

Besides PSM, POE (Power Over Ethernet) the application in communication domain is exceedingly wide also. POE can transmit data and power source through reticle. Lorry shares: “ADI had rolled out the solution of the POE of 150 tile now, the gain with this the biggest program is OK provide the power that is as high as 150 tile to the application of communication and layout. The far end that faces high-power equipment power supply, 150 tile can offer very perfect solution, this also is us in the platform of a technology with communication strong aspect. ”

 

Make form a complete set for system of efficient, clean, reliable the sources of energy

The sources of energy is the main topic of relation the national economy and the people’s livelihood. No matter to intelligent electrified wire netting, but second birth the sources of energy is generated and management of energy resources of memory, company, electric car charges picket infrastructure, ADI can offer program of very good technology of power source of form a complete set.

 

Graph 11: ADI has the plan of FCI of unit of monitoring of electrified wire netting of complete solar energy power supply

 

Common electrified wire netting is defeated by distribution to normally can such as FCI waits for supervisory equipment, but how be solved to the power supply of high-pressured report tower? Lorry explains: “ADI has very complete solution on this kind of FCI. Carry transformer or solar energy power supply normally, through high-powered MPPT most high-power dot dogs reach the application that fills electric management parts of an apparatus, batteries can achieve the biggest solar energy energy below same illumination circumstance. ”

 

Supply in electric power in, do not cut off the power to assure a system, ADI still puts forward to make backup power supply with super capacitance, offer complete energy memory and administrative program for it. For instance LTC3350, it does monitoring to 4 farad capacitance, can do to capacitance not only balance and fill / discharge management, return the internal resistance of additional electric capacity at the same time, and do energy automatically to all capacitance balanced, the function is very powerful.

 

Energy collects technical innovation, node of net of implementation content couplet is lifelong maintenance-free

 

Apparel to go to the lavatory of type equipment and node of terminal of net of more content couplet continuously in the light of intelligence power supply problem, ADI did rife exploration, can you wait for oscillatory, difference in temperature, smooth, magnetic field become the sources of energy of need? Also rolled out a series of innovation products for this ADI, if pursue 12.

 

Graph 12: ADI offers all ready energy to collect parts of an apparatus.

 

In addition, ADI also achieves a lot of major breakthroughs in other IoT direction. Detect through optics and motion for instance, potential of impedance, biology and signature grain technology bring up current world to be in wireless, can apparel life style asks for custody (the Medical Protection technology of the progress of VSM) . And detect through accurate situation, intelligent data is collected and the farm of wisdom of connective of interconnection farm ecosystem with the resource efficiency with own and decision-making, higher real time, handier implementation of sensor confluence technology.

 

Length of be confined to, the author cannot one-time present the splendid speech content of Lorry entirely, the summary that thinks final aid to bring a Lorry makes a speech: Brand of this stature of “Power By Linear reflected the development direction of future of ADI power product, what we consider is how to innovate, how to offer high-powered program, can provide the technical support with best whole world and best dependability and stability, help client extends his innovation domain in more heat and new sex market. ”
