摘要

The cascaded pulse power supply with the magnetic isolation is used to solve the problem of floating power supply of each cascaded unit.Its structure is compact and the trigger mode is simple and reliable.Using the trigger mode of magnetic coupling isolation can increase the tail branch in each concatenation unit simply and conveniently,reduce greatly the falling edge of output high voltage pulse,and improve the adaptability of cascade type pulse power.In this paper,a kind of 10 kV cascaded pulse power supply is developed.The rated working voltage of each cascaded unit is 1 kV for a total of 10 units.The voltage regulation range is 0-10 kV,the operating frequency is 1-10 kHz,the pulse current is 0-20 A,and the pulse width is 5-30 μs.%采用磁隔离触发式的级联型高压脉冲电源解决了每一级联单元浮动供电的问题，结构紧凑，触发方式简单可靠。利用磁耦合隔离的触发方式，触发信号一致性高，产生的截止偏压信号可以对绝缘栅双极晶体管进行可靠关断。同时，在每一级联单元附加切尾开关支路，降低输出脉冲高压的下降沿，提高级联型脉冲电源的适用性。研制的10 kV 级联型脉冲电源，每一个级联单元的额定工作电压为1 kV，总共10组。电压调节范围0～10 kV，工作频率1～10 kHz，脉冲电流0～20 A，脉冲宽度5～50μs。
