Half-bridge resonant converter, circuit using the half-bridge resonant converter, and corresponding control method

摘要

The half bridge resonant converter comprises a half bridge inverter having a high side switch and a low side switch, having an output defined from a node between the high side switch and the low side switch. The output is connected to the resonant circuit. There are separate control circuits with different reference voltage supplies for generating gate drive signals to control the switching of the high and low side switches based on the electrical feedback parameters.
