摘要：
This paper deals with inductive-resonant wireless power transfer (WPT) systems based on multilevel T-type inverters with simultaneous modulation of switching frequency and duty cycle. The effect of the hybrid modulation on the performance characteristics of closed-loop WPT systems with T-type multilevel inverters for wireless battery charging is studied in details by using simulation. Performance characteristics of the WPT system with the hybrid modulation are compared with that of WPT system without modulations and with classical switching frequency modulation. It is shown that T-type multilevel-inverter based WPT systems with hybrid modulation exhibit better performance than T-type multilevel-inverter based WPT systems with classical switching frequency modulation in terms of lower RMS and peak values of currents as well as better efficiency.
