In order to obtain the temperature field distribution of the all-film pulsed capacitors (AFPCs) under repetitive high-voltage pulse discharge conditions, we analyze the internal structure of the AFPC, and establish the temperature field simulation model. Based on the FEA, we obtain the overall temperature field distribution of the AFPC, and the relationship between discharge voltage, frequency, and temperature rise. This model can be used to evaluate the temperature rise characteristics of an AFPC in repetitive high-voltage pulse discharge and has certain guiding significance for the safe operation.
