Abstract:
A resonant power converter has a main switch, a resonant tank coupled across the main switch, and a signal processing circuit coupled to the main switch and the resonant tank. The signal processing circuit generates a driving signal for driving the main switch ON and OFF at a switching frequency. The resonant tank includes circuit components designed to have a resonant frequency that is tuned to a designed switching frequency of the main switch. The signal processing circuit includes a zero voltage switching (ZVS) circuit, a signal generator, a detection circuit, and a latch oscillator. The signal processing circuit is configured to adjust the switching frequency of the driving signal to be tuned to the actual resonant frequency of a resonant tank under very high switching frequency conditions, 1 MHz and greater, thereby accounting for the influence of parasitics at very high switching frequencies and achieving resonance of the circuit.

Claim (Index 1):
A resonant power converter comprising:\n a. a transformer having a primary winding and a secondary winding, wherein the secondary winding is coupled to an output of the resonant power converter; b. a switch coupled in series to the primary winding; c. a resonant tank coupled in parallel across the switch; and d. a signal processing circuit coupled to the resonant tank and to the switch, wherein the signal processing circuit is configured to generate a driving signal having a switching frequency to drive the switch, to sense a voltage across the resonant tank, and to selectively adapt the switching frequency according to the sensed voltage across the resonant tank so that the switching frequency is tuned to the resonant frequency of the resonant tank.
