Electric machinery starter the 6th part: Frequency conversion driver

Electric machinery starter the 6th part: Frequency conversion driver

[introduction]When using the applied program that does not need to move amain, frequency conversion driver can reduce cost of specific power consumption. The purpose of VFD is to make the speed of the equipment of electric machinery drive and the speed look that want load match. Driver of other alternating current cannot realize this. Why should use electric power drive? When using the applied program that does not need to move amain, frequency conversion driver can reduce cost of specific…

Reduce the deposit of resistor of semiconductor metal thread and quarter corrode technology

Reduce the deposit of resistor of semiconductor metal thread and quarter corrode technology

[introduction] system structure, interstitial bulk, crystal boundary and material interface break resistor rate You Jijing of copper match a decision, follow measure is narrow and remarkable promotion. Normally, the making flow of copper cash is to use groove to engrave corrode craft to be in low interpose report cuts corrode groove figure in 2 oxidation silicon, use cupreous fill groove through Damascus flow next. But the much crystal structure that this kind of method can give birth to to contain…

Electric car charges quickly the efficiency of converter of DC/DC of systematic segregation type is the biggest change

Electric car charges quickly the efficiency of converter of DC/DC of systematic segregation type is the biggest change

[introduction]Inside global limits from internal-combustion engine car (ICE) turns to electric car (the condition of EV) is corresponding charge infrastructure obtains significant progress. Although low power (<15 KW) car carries charger to be able to support a family to charge during car is unused, but long-distance journey and service industry need are faster charge speed, with gas station of current to mark gas cheer speed. Charge to rise speed, need improves batteries at the same time technology and charge infrastructure….

Use operation amplifier breaks up voltage course in order to found fictitious ground

Use operation amplifier breaks up voltage course in order to found fictitious ground

[introduction]The likelihood in the design includes the sensor that needs ambipolar power supply or IC, or you need to make full use of converter of ambipolar input modulus (the dynamic limits of ADC) . Another reason that breaks up voltage course is, if you are in design of course of only power source,need intermediate course bias voltage. The likelihood in the design includes the sensor that needs ambipolar power supply or IC, or you need to make full use of…
