PV Based ZVZCS Current Control DC/DC Bridge Converter for Battery Charging

An PV based DC/DC Boost converter is increases the DC voltage used to charge the traction battery in an electric conveyance. Photovoltaic cells provide an additional method of acquiring energy, converting sunlight directly into electricity through the use of dc / dc converter. The conventional topological failed to operate the converter with zero current and zero voltage switching during no load condition resulting high voltage spikes in the output voltage. In order to attest reliable operation of the bridge converter under wide load variations, the converter should not only operate with soft-switching from no-load to full-load condition, but additionally from full-load to no-load condition making gamut of operation for achieving such stringent requisites and high reliability, the converter employs a symmetric passive way near lossless auxiliary circuit to provide the reactive current for the full-bridge semiconductor switches, which guarantees zero voltage switching at turn-on times for all load conditions. This is a current driven topology in accumulation with a voltage multiplier in order to clamp the output voltage and additionally slake ZVZCS operation of the converter resulting in high voltage gain.
