The existing pulse power supply mostly adopts a unit modular design, and each pulse power supply module is an independent power supply. The output current of the single power supply assembly is limited, and for working conditions exceeding the upper limit of the output current of the single power supply assembly, a power supply assembly group is often formed by a plurality of power supply assemblies, and discharge is carried out simultaneously to meet the output current requirement. The upper limit of the discharge frequency of the power supply assembly group is determined by the discharge frequency of the single power supply assembly, and the discharge frequency of the power supply assembly depends on the thermal load characteristic of the pulse thyristor type high-current switch. In order to meet the requirement of high repetition frequency output current, the prior art conducts a plurality of power supply components in a time-sharing way, so that the heat load of the pulse thyristor type high-current switch is reduced, but the mode requires a large number of power supply components, and the design cost of the device is increased. Meanwhile, due to the fact that the heat load difference of the pulse thyristor type high-current switch is caused by design errors in the design process of the power supply assembly, part of the power supply assemblies can reach the upper limit of the heat load first, and normal operation of a pulse power supply system is affected.
