[introduction] traditional diesel locomotive use car with mixture report (HEV) or electric car (EV) one of a between main distinction are existence knaggy batteries and voltage grade. Internal-combustion engine by individual 12V or 24V batteries (it is plumbic acerbity batteries normally) move. But, the limits of the cell of 2 high pressure that HEV and EV use from 48V (HEV) come to taller voltage 400V 800V (EV) .   The existence need segregation of much voltage n will protect low-pressure…

[introduction] because we must use many power level, realize tall gain at the same time consequently (1000 – V/V and even taller) with tall bandwidth (tens of MHz) the likelihood is a kind of challenge. Besides the circuit requirement of respect of tall gain, tall bandwidth, still need to pay close attention to noise and stability problem mainly.   Examine next figures, understand the overall framework of 3 class amplifier.     The noise that every successive amplifier produces and…

[introduction] be in before “ tall gain, tall bandwidth, how both hold concurrently? In one article of ” , while if why realizing tall gain and tall bandwidth,we were discussed, still can keep enough tall letter a confusion of voices is compared (SNR) . We discuss more detailed ground executive method and the issue that produce possibly in this article.   Because target gain is very tall, need to check dc above all (the circumstance that DC) works, whether output…

[introduction] warm when information of user credit card and establishment an air conditioning (HVAC) systematic connection, the brim and embedded the main influencing factor that the security of processing makes construction of system. Can adopt a variety of methods to enhance the security in data storage environment, but doing not have a kind of method is no risk at all.   Much chip module (MCU) / enclose safe processor jointly / communication is compositive–Safe challenge   Warm when information of…

[introduction] speak of to need minute of line, do high speed design to should not know without the person. The biggest acknowledge is interference rejection ability strong. To drawing circuit board for, the collateral bus line of the root that compare sheet is simple. Be like: PCIE of a big line comparing differs DDR a few pairs the trouble that distribute a line became much.   —— of the line that need branch needs a standard, in all model, strange…

[introduction] as batteries chemistry character, dependability and relevant technology stable with each passing day, car batteries runs a system (BMS) the design also develops ceaselessly subsequently. Nowadays, if where,BMS design personnel had mastered electric the optimum behavior that BMS all is optimized to measure below environment of very harsh drive a vehicle and implements a system with exterior condition.   As batteries chemistry character, dependability and relevant technology stable with each passing day, car batteries runs a system (BMS) the…
