Abstract :
A high-efficiency power converter has been developed that provides high-voltage pulses to inductively-driven electric propulsion engines for long-duration space travel. High electrical efficiency is achieved using a novel ring topology that recovers unused energy at the load end of a pulse-compression chain. Voltage reversal on energy-storage capacitors is eliminated in the ring topology, resulting in long capacitor lifetimes. System tests were performed at 3.3 kV with a peak current of 20 kA and a current switching rate of 15 kA/mus.
