This book is inductive power transfer (IPT) in power electronics. In order to improve the coupling coefficient, improve the quality factor, and control the harmonics, the method of analysis and design of the IPT system is proposed. By increasing the coupling coefficient of the magnetic coupling structure and improving the quality factor of the system, the efficiency of the system is improved and the distance of IPT is extended. The applicable readers are scholars, undergraduates and postgraduates in the field of power electronics.
