Abstract

Abstract: High efficiency chargers having high power are required to charge the batteries of light electric vehicles. This work proposes a single-power-conversion battery charger without a bridge made up of a boost AC-DC converter that is isolated and with a circuit having resonance in series to suit this need. The circuit with a series resonance decreases by offering zero current switching, you may reduce output diode recovery losses, while conduction losses associated with the input diode rectifier are reduced by using a bridgeless arrangement. Furthermore, injection of current by direct and series-resonance allows the transformer to excite the core in both directions, providing for high power capabilities (Lakshmi and Hemamalini (2019) and Haghbin et al. (2013) [1, 2] ). In conversion of power using single stage, the feedback linearization-derived control algorithm is also built, allowing the suggested charger for power factor correction and output power regulation. This straightforward circuit construction results in good efficiency and a large power factor. The proposed charger's ideas that are theoretical are tested in an actual setting with a 1.7 kW prototype.
