  • Half bridge resonant converters, circuits using them, and corresponding control methods
    Patent number: 10389260
    Abstract: A half bridge resonant converter comprises a half bridge inverter having a high side switch and a low side switch with an output defined from a node between the high side switch and the low side switch. The output connects to a resonant circuit. There are separate control circuits for generating the gate drive signals for controlling the switching of the high side switch and low side switch, in dependence on an electrical feedback parameter, each with different reference voltage supplies.
    Type: Grant
