NOVEL SYSTEM OF WIRELESS POWER TRANSFER FOR BATTERY CHARGING OF EV APPLICATIONS USING QUASI ZSI

This research describes a 60-kW quasi-impedance source-based inductive type wireless power transfer quick charging system. The suggested system comprises of a quasi-Z-source converter (needed to raise the input voltage), a high-frequency inverter, and an inductive coil with capacitive compensation. At the receiver end, a buck converter is installed, which is operated in Constant Current (CC) or Constant Voltage (CV) charging modes based on the State of Charge. Two different PI controllers are used to achieve both CC and CV. The suggested system generates 60 kW of power at 135A, charging the battery from 0 to 80% SOC in less than 30 minutes. The simulation results achieved using MATLAB are consistent with the commercial guidelines for the battery charging process. Detailed simulation outcomes are provided, helping us to take use of many characteristics of the intended charger.
