发动机采用高压直流电驱动，电流转换通过直流-直流转换器实现。
The motor is powered by high voltage DC supply and the current from the fuel cell system is regulated via a DC DC converter.
对于直流电流测量﹐在电流通道串联一电流分流器﹐将电流转换成直流电压信号。
For DC current measurement, a current shunt is place in series in the current path and convert the current to a DC voltage signal.
该电源输入单一交流电压和频率，内部经过交流对直流；直流对交流的变流整流转换后，自行产生-非常稳定纯净的正弦波。
The single AC power input voltage frequency, the internal AC to DC after; DC converter rectifier exchange conversion, self-produced - very stable, pure sine wave.
