A zero-voltage switched PWM boost converter with an energy feedforward auxiliary circuit
A zero-voltage switched (ZVS) PWM boost converter with an energy feedforward auxiliary circuit is proposed in this paper. This converter can be operated with PWM control because ZVS operation is achieved with an auxiliary resonant circuit that has few switching losses and handles much less power than the main power circuit as it is activated for only a small fraction of the switching cycle. Moreover, peak switch stresses are lower than those found in other proposed converters because some of the energy circulating in the auxiliary circuit is fed to the load. In the paper, the modes of converter operation are explained and analyzed, design guidelines are given, and experimental results are presented.
