A single-switch fully-controlled three-phase rectifier is presented, which provides high AC power factor and wide DC voltage regulation while allowing high-frequency insulation. Owing to one-cycle control, output voltage ripple is also eliminated. Moreover, switch voltage stress is limited by a lossless clamper circuit, resulting in safe operation and high efficiency.

Abstract
A single-switch fully-controlled three-phase rectifier is presented, which provides high AC power factor and wide DC voltage regulation while allowing high-frequency insulation. Owing to one-cycle control, output voltage ripple is also eliminated. Moreover, switch voltage stress is limited by a lossless clamper circuit, resulting in safe operation and high efficiency.
