Ripple feedback for the resonant-filter unity-power-factor rectifier

An unusual bucklike 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 is potentially unstable with real...

Zusammenfassung:An unusual bucklike 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 is potentially unstable with realistic values of AC-line impedances. A new ripple feedback is proposed that solves both problems. 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 500 kHz rectifier operating from the 120 V, 60 Hz distribution system.< >
