Overall Loss Compensation and Optimization Control in Single-Stage Inductive Power Transfer Converter Delivering Constant Power

Fei Xu et al.

Summary: This paper optimizes the system efficiency of a single-stage inductive power transfer charger by minimizing overall losses using a constant-power charging scheme. The conditions of zero voltage switching and minimum circulating reactive power are derived, and the power losses in different components are analyzed and optimized under constant-power output condition. A novel optimal control strategy is proposed to maintain constant-power output and maximum efficiency throughout the charging process.

An Inductive Coupler Array for In-Motion Wireless Charging of Electric Vehicles

Vahid Zahiri Barsari et al.

Summary: The article introduces a simple and robust push-pull driven coupler array (PPCA) to decrease the number of switches required for driving in-road couplers in dynamic IPT systems. This configuration allows for independently energizing multiple primary IPT couplers without proportionally increasing current stress on the switches, improving the system's reliability and economic feasibility.
