Abstract According the problem of reverse surge overcurrent in the pulse power source, the equivalent circuit of pulse forming network with output rectifier bridge of charger was established. The mechanism of circuit working was discussed, the reason of overcurrent burnout of rectifier bridge was analyzed, and the method of restraining reverse surge overcurrent was put forward. The results show that the parallel connection of the charger's rectifier bridge and the pulse capacitor changes the topology of the pulse forming network, and the branch of the rectifier bridge starts to turn on at the stage of switching. Under the influence of distribution parameters of the circuit, the instantaneous surge current will be generated. The thyristor is not turned off after switching. The capacitor is continuously charged and discharged through the thyristor branch. The method of series connection of high power and small resistance damper resistance in rectifier bridge branch can effectively reduce surge overcurrent, turn off thyristor normally, release capacitor's reverse voltage through rectifier bridge branch, and prolong the service life of capacitor. The experimental results show that the damping resistance can effectively reduce the reverse surge overcurrent, and the rectifier bridge is not damaged again. This method is helpful to improve the reliability of compact pulse power source and provides a reference for the design of subsequent pulse power system.
