Abstract

A converter circuit (100) includes a primary side (102) having a resonator and a first control circuit (116) configured to control the resonator. The converter circuit also includes a secondary side ( 104) having a resonant rectifier and a second control circuit (118) configured to control the resonant rectifier. The converter circuit further includes a transformer (106) configured to electrically isolate the primary side from the secondary side. The second control circuit (118) is configured to turn the resonant rectifier on and off. The first control circuit (116) 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 (116) 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. 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.
