Abstract
The current source AC/DC converter with energy recovery snubber circuits has been expected for applications of superconducting magnetic energy storage and DC transmission system because of its high efficiency and easiness for large capacity. In this paper, characteristics of this AC/DC converter under the sinusoidal pulse width modulation control were studied by both computer simulation and experiment. The characteristics were compared with typical current source type PWM converter on converter losses and distortion of AC current waveform.
