Abstract:
Various improvements are provided to resonant DC/DC and AC/DC converter circuit. The improvements are of particular interest for LLC circuits. Some examples relate to self-oscillating circuit and others relate to converter circuits with frequency control, for example for power factor correction, driven by an oscillator.

Claim (Index 9):
A conversion method, comprising:\n operating a half bridge inverter comprising a high side switch and a low side switch using a gate drive signal and providing an output from a node between the switches, wherein a high gate drive signal turns on one switch and turns off the other switch and a low gate drive signal turns off the one switch and turns on the other switch; providing an electrical feedback parameter from an LLC circuit coupled to the output; and controlling the switching of the high side and low side switches in dependence on the electrical feedback parameter, by:\n setting a threshold level proportionally to the converter output voltage or current and a rectified input voltage in an outer control loop; and \n in an inner control loop which comprises an oscillator for generating the gate drive signal, setting an oscillator frequency based on an average value of a comparison between the threshold level and the electrical feedback parameter.
