摘　　要：采用电容作为储能元器件,气体放电管作为脉冲开关,设计了低频高压脉冲放电水处理电源。结合电流电压双闭环负反馈控制方法,设计了绝缘栅双极型晶体管(IGBT)逆变直流充电电路,可对储能电容进行恒压限流充电。基于PIC16F72单片机,研制了专门的放电触发时序控制电路,实现了3路高压脉冲放电电路交替放电,脉冲电源放电频率可达200Hz。将该高压脉冲电源应用于日落黄模拟印染废水处理,降解效果显著。A low frequency high voltage pulsed discharge power supply used in wastewater treatment is designed by using capacitors as energy-storage elements and gas discharge tubes as pulse switches.Combined with the control method of double closed loop feedback, insulated gate bipolar transistor（IGBT） inverter DC charging circuit is design- ed,and it can charge the energy-storage capacitors with constant-voltage and limited-current.Based on the MCU PIC16F72, a special discharge triggered timing control circuit is developed, and three high voltage pulse discharge cir- cuits can discharge in turn, making the discharging frequency be 200 Hz.Using this power supply to deal with Sunset Yellow wastewater, the degradation effect of Sunset Yellow is significant.
