Open Loop Control of The Z Source Resonant Converter for the Electric Vehicle Wireless Battery Charger

Abstract

Wireless charger for Electric Vehicles (EVs) is an off-line application and it needs power factor correction (PFC) function, which usually consists of a front-end boost PFC and a cascaded DC/DC converter. Recently, Z-source resonant converter (ZSRC), a single-stage solution with low cost and high efficiency, was proposed for EV wireless charger. Combining with the Z-source network, the control scheme is more challenged and sophisticated. The experimental setup is done for the open loop control of the z source resonant converter. The pic microcontroller is used for the generating the pulse gate for the MOSFET and the conductor coils are used for the wireless power transmission, The experiment is done for the 33v input dc and the 88v dc output voltage prototype.
