Study on the Pulse Transformer with energy recovery for Repetitive Pulsed High Magnetic Field

As the frequency of repetitive pulses is limited by the low efficiency of the energy supplement, the scheme of multimodule power supplies which can produce the multi-pulse with tens of Hz is proposed. An energy recovery circuit main composed of a pulse transformer is used to reduce the requirements of the energy supplement. The structure of the pulse transformer with the coupling coefficient 0.6 is designed, and the inductance of primary winding and secondary winding are the same. In order to obtain the structure parameters accurately, a particle swarm optimization support vector machine (PSO-SVM) is selected to provide design principles. With the participation of the transformer, the energy conversion efficiency between the two capacitors is 66.28 %, which can save 80 % replenish time of recharging.
