over a wide range of load the power is regulated with high efficien cy by inductively coupled power transfer system. In this paper a novel harmonic based phase-shifted control method is proposed. With this method, the resonant inverter output voltage is employed to regulate the output power. By changing the phase-shifted angle of inverter the output power is regulated. The switching frequency is much lower than the fundamental frequency which is different from conventional approaches; therefore the switching losses are very less. The principle of operation, switching strategy and the effect of dead time ha s all been presented. Experimental results says that the proposed power regulate method can achieve improvement at the light load condition.
