Abstract

Photovoltaic applications require regulation by high performance dc-dc converters since the dc voltage generated is normally unregulated and depends heavily on load and ambient conditions. In this paper, a ZV-ZCS full-bridge phase-shift PWM dc-dc converter is being proposed for photovoltaic cell applications. The proposed converter operates at high switching frequency with high efficiency and large power to volume ratio. A laboratory prototype model of the proposed converter has been designed and fabricated for charging a 48 V battery bank for telecommunication applications from a solar panel with 110 V open circuit voltage. The experimental results were found in close agreement with the predicted soft-switching behavior of the converter.
