  • Apparatus and method for synchronous rectifier control delay
    Patent number: 11804784
    Abstract: A circuit for use in an LLC converter comprises a first primary side switch, a first secondary side switch assembly, and a controller. The controller is configured to measure, on the primary side of the LLC converter, a first voltage and determine, based on the first voltage, a delay due to the first voltage. The controller is also configured to apply a first gate voltage to the first primary side switch to transition the first primary side switch from an off state to an on state and apply a second gate voltage to the first secondary side switch assembly to transition the first secondary side switch assembly from an off state to an on state. The application of the first gate voltage and the application of the second gate voltage are separated by a synchronous rectifier delay based at least on the delay due to the first voltage.
