chopped by the chopper to convert it into high frequency ac signal. This signal is fed to an isolating highfrequency transformer. The ac output current from the transformer is rectified and filtered to obtain load independent dc outputcurrent. As the transformation ratio is 1:1 the output current is identical in value to the dc input current.
输入信号被过滤，处理转而变为一个标准直流电压。这电压被喂一个线性变送器哪提供要求隔离电流。用于改善线性，响应时间，温度效应。产出从线性变送器更远的的过
