Abstract :
The properties and applications of power electronic converters with voltage conversion ratios that are quadratically dependent on the duty ratio are discussed in this paper. A novel, soft-switched, three-phase, single-switch quadratic buck converter is also proposed. The converter is a zero-current- switching (ZCS) quasi-resonant type converter that can operate with significantly less switching frequency variation because of the quadratic nature of the converter. The operating principle of the proposed converter is explained, its operating modes along with key waveforms are shown and simulated results are presented in the paper.
