Abstract

Three phase simultaneous current pulse control for a high frequency series resonant DC link converter was achieved by utilizing a previously developed pulse trimming method and current peak limiting with a saturable core. Each resonant pulse is split to flow in three phases almost at the same time so that a very smooth sinusoidal output current waveform is attained. The duality of the series resonant DC link with the parallel resonant DC link is discussed. Simulation and the basic experimental results are presented
