摘要： A converter circuit includes a primary side having a resonator and a first control circuit configured to control the resonator. The converter circuit also includes a secondary side having a resonant rectifier and a second control circuit configured to control the resonant rectifier. The converter circuit further includes a transformer configured to electrically isolate the primary side from the secondary side. The second control circuit is configured to turn the resonant rectifier on and off. The first control circuit may be configured to detect when the resonant rectifier is off and, in response, turn the resonator off without using a feedback signal from the secondary side. The first control circuit may be configured to detect when the resonant rectifier is off by detecting when input power to the primary side decreases. The resonant rectifier could be turned on and off by detuning the resonant rectifier.

摘要： A gate driving circuit includes a driving stage configured to receive an input signal and generate a gate drive signal for a gate of a transistor switch. The gate driving circuit also includes an LC circuit having an inductor and a gate capacitance of the transistor switch. The LC circuit is configured so that a pulse in the gate drive signal generates a ringing in the LC circuit at a resonance frequency of the LC circuit to transfer energy into and out of the gate capacitance of the transistor switch. A switch could selectively couple the gate of the transistor switch to ground in order to discharge the gate capacitance. A control circuit could be used to provide the input signal, and the control circuit could be configured to regulate a duty cycle of the gate drive signal by adjusting an off-time between consecutive pulses in the input signal.
