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 1):
A converter, comprising:\n a half bridge inverter comprising a first switch and a second switch, wherein a first output is defined from a node between the switches; an LLC circuit comprising a second output for supplying an output voltage and an output current, and being coupled to the first output, wherein an electrical feedback parameter is provided by the LLC circuit; a control circuit for generating a gate drive signal for controlling the switching of the first switch and the second switch in dependence on the electrical feedback parameter, 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, wherein the control circuit comprises: an outer control loop for setting a threshold level proportionally to at least the converter output voltage or current; and an inner control loop comprising an oscillator for generating the gate drive signal and a comparator for controlling a frequency of the oscillator based on an average value of a comparison between the threshold level and the electric feedback parameter.
