Abstract

This paper explains a procedure on how to select resonant circuit components of a unique direct three-phase to single-phase AC/AC converter for a contactless electric vehicle (EV) charger. The topology has a fewer bi-directional switches than a matrix converter and consists of a resonant circuit to utilize a zero-current switching (ZCS) mechanism. The selection goal was to realize a working prototype that does not violate each electrical component's limitations as well as has a low resonant damping ratio since the switches are driven based on a resonant current. Selection methods were based on graphical analysis of damping factor, resonant frequency, and primary circuit voltage and current characteristics derived from dynamic and steady-state models. Simulation results are then presented to validate the selection procedures.
