摘　　要：采用双管正激交错并联结构设计输出电流连续可调的DC/DC变换器恒流源,主电路后级电路不用电阻限流,也不用电感限流,而是利用前级DC/DC变换器以及脉冲控制发生电路共同作用来控制后级电路中的加工电流。The self-adaptive non-resistance high frequency pulse power supply is designed using the parallel two-transistor forward DC/DC converter. The output current can be modulated to a certain extent. Not only resistance but also inductance is not used in the main circuit of non-resistance pulse generator. It depends on the DC/DC converter and control circuit to codetermine the machining current.
