<Abstract>

This paper presents a design of the pre- and post-regulation magnetic-resonance WPT system with Class-D rectier. The class D rectier has no capacitance components in its operation, which can be expressed by only the equivalent resistance. This means that the reactance-component variations do not yields when the class-D rectier is applied to the receiver part of the pre- and post-regulation WPT systems. The experimental results show that the proposed system is effective for coil misalignments compared to the Class-E2 WPT system．
