Abstract
An unusual buck-like unity-power-factor rectifier with a resonant load-balancing network permits current-limited operation down to zero output voltage in a single-stage topology. However, this rectifier has been found to be sensitive to AC-line voltage distortion, and potentially unstable with realistic values of AC-line impedance. A ripple feedback which solves both problems is proposed. A large-signal time-varying analysis is given along with incremental, quasi-static and low-frequency approximations. Experimental verification is provided by a 500 W, 50 kHz rectifier operating from the 120 V, 60 Hz distribution system.Keywords
