Abstract：In an inductive coupled power transfer (ICPT) system, static compensation couldn’t give attention to power transfer performance and zero phase between power source current and voltage. To solve this problem, a dynamic compensation method is proposed in this paper. With a controlled reactor and a fixed capacitor connected in parallel, the primary coil is tuned dynamically, and the secondary coil is compensated with a static capacitor. A pair of anti-parallel power switches is used to control current through the controlled reactor to obtain zero phase angle condition. Reactor and capacitor parameters are deduced and optimized with different compensation topologies of the secondary side. PSpice simulations are carried out for dynamic compensation and static compensation respectively. Theory analyze and simulation results indicate that compare with static capacitor compensation, dynamic compensation achieved zero phase angle between power source current and voltage on rating frequency, demand for power supply rating is reduced and power transmission performance is ensured.
