The DSP realizes functions of sampling, PI regulation, communication and so on to digitally control the excitation current of arc-suppression coil with magnetic bias.
DSP主要完成采样、PI调节和通信等,实现偏磁式消弧线圈励磁电流的数字控制。
In the scheme we designed effectively high voltage control circuit. It works accurately to digitally control the testing voltage and testing current.
