Abstract：In this paper, an active residual energy recovery method is proposed for inductive pulsed power supply based on high temperature superconducting pulse transformer (HTSPPT). This method can recover the leakage energy in the initial discharge stage by using a bridge-type capacitive switching circuit. When the load current pulse width reaches the requirement, the recovered leakage energy can be used to change the voltage polarity of the secondary inductor, make the load current cut off quickly, and transfer the residual energy to the primary inductor. The simulation and experimental results show that the method can cut off the load current and recover the residual energy quickly with the controllable cut-off time of the load current. The experimental results and simulation results agree with the theoretical analysis, which shows the effectiveness of the method.
