Abstract

This paper suggests the circuit topology to transfer AC power using a detachable transformer The circuit topology for AC output load through the magnetic coupling and its principle of operation are described. It can decrease the size of detachable transformer by employing the high-frequency magnetic coupling. It is shown in this paper that the efficiency of noncontact energy transfer system can be improved by applying both the full bridge converter with PFC function to the 1st side of its and the series resonance to the 2nd side to minimize the effect of the leakage inductance.
