Abstract

A three-phase resonant inverter for wireless power transfer applications is presented in this paper. A phase-frequency hybrid control strategy is proposed as an alternative to the traditional frequency and phase control methods. An experimental prototype of the three-phase resonant inverter was built and connected with wireless power link and rectifier. The hybrid phase-frequency control strategy was implemented and compared with frequency control at the output power up to 10 kW. The experimental results show that the proposed inverter can operate within the desired frequency range with high efficiency while regulating output from zero to maximum.
