摘　　要：负高压电源系统是ECRH系统的重要组成部分,其信号的传输是整个系统运行的关键。文章介绍了一种利用V/F(Voltage/Frequency)和F/V(Frequency/Voltage)转换器实现ECRH(ElectronCyclotronResonanceHeating)负高压电源系统信号隔离传输的方法,设计了基于DMC5501和DMC5502转换器的硬件电路。实验结果表明,该方法有较好的稳定性和可靠性,能满足高压隔离和抗干扰要求,达到了预期目标。High-voltage power supply(HVPS) is one of the important component in ECRH (Electron Cyclotron Resonance Heating).The signal transmission is a key of the operation of the whole system .A realization method of signal-isolated transmission in the HVPS system of ECRH using V/F(Voltage/Frequency) and F/V (Frequency/Voltage) converter is introduced. Hardware circuit based on DMC5501 and DMC5502 are given. The results of experiment show that the method has better stability and reliable. It can meet our requests and reach the expected goal.
