Inductive Energy Transfer Using a Flying Capacitor

Abstract

A new inductive energy transfer system for fusion reactor technology using superconductive coils is proposed. Transfer is achieved stepwise by a small thyristor-switched capacitor between the inductances. The system is highly efficient and allows return of the transferred energy. Transfer times are in the one-second range. A superconductive 10 kJ model was designed and built. In tests, 80% of the stored energy was transfered into a load within 0.5 seconds.
