Pre- and post-regulation control of high-frequency magnetic-resonance wireless power transfer system with class-D rectifier <Abstract> This paper presents a design of the pre- and post- regulation magnetic-resonance WPT system with Class-D rec- tifier. The class D rectifier 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 rectifier 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-E 2 WPT system with pre- and post-regulation control . |
