Abstract

A novel soft-switched push-pull boost converter is proposed for use as the front end converter of the uninterruptible power supply. The proposed soft-switched topologies and technologies have advantages of unity power factor, low current and low voltage stresses, small size, light weight and high efficiency. A stabilized power P_S is introduced for stabilizing the output voltage. Experimental results of the proposed soft-switched push-pull boost converter are presented for verifying the proposed topologies and the analytical methods
