Abstract:
A circuit for energizing a load, comprising:a rectifier for receiving an AC input signal and providing a DC output signal, the rectifier including a first rectifying diode;a resonant inverter for receiving the DC output signal and providing an AC drive signal to the load, the resonant inverter includinga first current path through which current to the load flows; anda second current path through which reactive current flows, the second current path including a feedback capacitor; anda feedback signal path extending from the feedback capacitor to the first rectifying diode, the feedback signal path including a feedback inductor, wherein the feedback capacitor and the feedback inductor resonate in series such that resultant voltages on the feedback capacitor and the feedback inductor combine to provide a feedback signal on the feedback signal path for linear operation of the first rectifying diode.
