Abstract：A phase shifting-short control strategy for π-type resonant inductive power transfer (IPT) system is proposed to solve the issue which is hard to regulate power for output while parameters and input power of current-fed IPT system is fixed on. To regulate the power for output effectively the short-time of the full-bridge inverter is adjusted, at the same time, extending output power range. The duty cycle of single bridge is defined, base on analyzing model of resonant circuit and model of steady state for system. The relationship between the duty cycle and output power of system is derived. Finally, experimental results and simulation results verify the validity of conclusions for phase shifting-short control strategy.
