Patent abstract
A driver circuit (e.g., an LED driver circuit) provides power to a load (e.g. an LED light source) from a DC power rail. A self-oscillating LLC series resonant inverter is configured to connect to the DC power rail, receive DC power from the DC power rail, and provide an AC output signal. A current limiting capacitor is connected to the self-oscillating LLC series resonant inverter. The current limiting capacitor receives the AC output signal from the self-oscillating LLC series resonant inverter and provides an AC current signal. The rectifier circuit receives the AC current signal from the current limiting capacitor and provides a DC current to the load.
