Improving efficiency of the active-clamped SEPIC rectifier at high line frequencies

Abstract

The performance of a conventional isolated SEPIC rectifier can be improved with an active voltage clamp. Relatively high efficiency and low total harmonic distortion (THD) can be achieved with an active-clamped SEPIC rectifier in high-line-frequency (360-800 Hz) avionics applications. However, it is observed that a diode conduction problem affects the… (More)
