摘要
A full bridge circuit is disclosed. The full bridge circuit includes first and second half bridge circuits each having a midpoint node, and a transmitter tank circuit connected across the midpoint nodes and configured to transmit power based on the transmitter tank current to a load. The full bridge circuit also includes a ZVS tank circuit connected across the midpoint nodes. The ZVS tank circuit generates first and second ZVS tank currents. The first ZVS tank current and the transmitter tank current cooperatively cause the voltage at the first midpoint node to be substantially equal to the voltage of a power or ground node, and the second ZVS tank current and the transmitter tank current cooperatively cause the voltage at the second midpoint node to be substantially equal to the voltage of the power or ground node.
