Abstract

This paper aims to present a loss model and investigate the stability of a LCL-IPT system for EVs. For the experimental set-up and loss model, Silicon Carbide MOSFETs have been used as the converter switches. The zero-voltage-switch contour area of the converter over the entire operation range is presented and the optimum dc-link voltages for efficiency maximization are also shown. The stability of the system consisting of a single pickup, is investigated to highlight potential issues. Voltage-cancellation technique is utilized to control both the primary and secondary side currents.
