Abstract
A boost converter which employs an isolated active snubber to reduce the lo sses caused by the reverse-recovery characteristic of the boost rectifier a nd the turn-on discharge loss of the output capacitance of the boost switch is described, The proposed isolated active snubber consists of a coupled i nductor, clamp capacitor, and ground-referenced n-type MOSFET. The performa nce of the proposed converter is evaluated on a 1-kW, universal-line-range, boost input-current shaper.
