Abstract
A resonant inverter with a self-oscillating driver IC for powering AC loads, such as gas discharge lamps or regulated DC/DC converters, includes a timing circuit that generates control strobe pulses that are injected into the timing circuit. The timing circuit is coupled to an inverter resonant tank through a feed back circuit providing phase lock for the resonant inverter. The feed back circuit connects the resonant tank circuit to a zero signal detector. The feed back circuit includes a phase compensator and a controller that has a source of a bias current connected to the zero signal detector.
