Abstract :
This paper presents a novel high efficiency topology that is capable of operating with lossless switching though a very wide load range. The topology exhibits practical efficiencies exceeding 97% for a 250W, 50V output, and presents an optimised, smooth switching waveform, which is ideal for a typical spacecraft electronic power conditioner
