Secondary-Side Output Boost Technique in Power Converters and Wireless Power Transfer Systems

摘要

In one embodiment, a power converter includes a wireless transmitter coil and a resonant capacitor that is configured to resonate at a first frequency. The wireless transmitter coil and resonant capacitor are configured to receive an alternating current at a second frequency such that the power converter outputs a first voltage that is dependent on the second frequency. In one embodiment, the first and second frequency are substantially equal. The power converter may also include an interconnection link configured to substantially double or vary the first voltage depending on a duty cycle that is applied to the interconnection link.
