Design and Simulation of An Energy Recovery Circuit for Repetitive Inductive Pulsed Power Supply

The use of high-temperature superconducting pulsed power transformers (HTSPPT) for repetitive pulsed power supplies has been demonstrated. However, this type of inductive pulsed power supply (IPPS) has a problem that cannot be ignored, that is, it has more residual energy that is difficult to recover when facing inductive loads. In this paper, a residual energy recovery circuit unit is designed for this type of repetitive IPPS for inductive loads. With this circuit unit, the residual energy of the secondary inductors can be recovered and reused for the next discharging phase. To illustrate this circuit, simulations were carried out. The results show that the circuit can reduce the falling time of the load current pulse in the case of inductive load.
