Simulation and comparison of selected fast charger topologies

Abstract

The article reviews the role of fast chargers in swiftly developing area of electrical energy storage devices. Energy efficient techniques implemented in fast chargers are shown, world standard requirements are mentioned. The models of the two topologies of the greatest interest: soft switched rectifier with diodes at the secondary side and synchronous rectifier are carried out and the results of simulations are presented. Higher efficiency of synchronous rectifier is proven.
