Design and Sensitivity Analysis of Dynamic Wireless Chargers for Efficient Energy Transfer

Tunable Self-Oscillating Switching (TSOS) methods are a robust solution for tuning of Inductive Power Transfer (IPT) systems. However, they require deep analysis to be an appropriate choice Dynamic Wireless Charging (DWC) In this paper, the optimal operation point TSOS in maximum power transfer, efficiency, and Zero Voltage (ZVS) realization perspectives determined based on sensitivity DWC Electric Vehicles (EVs). analysis, all possible states coupling factor state charge (SOC) considered as system variables. Moreover, new phasor modeling constant voltage (battery) loads is proposed. The performance model quite different from conventional static loads. limit current charger under light couplings, simple hysteresis controller employed. A setpoint proposed method transfer energy misaligned conditions. increases transferred efficiency while limits charger. To analyze method, simulation done Simulink/MATLAB, verify results, laboratory prototype implemented.
