ABSTRACT:
In one aspect, the invention provides a power system for providing power to a load. In some embodiment, the system comprises: a rectifier configured to rectify an AC main signal to produce a rectified AC main signal; a zero cross detector configured to receive the AC main signal and to detect when the AC main signal equals zero; a switching device having (i) a first terminal connected to a first node, wherein a first output terminal of the rectifier is also connected to the first node and (ii) a second terminal connected to a second node; a tank circuit having (i) a first terminal coupled to a third node, wherein a second output terminal of the rectifier is also coupled to the third node and (ii) a second terminal coupled to the second node; a current and/or voltage detector connected to the second node; and a controller in communication with the current detector and zero cross detector and configured to turn on and off the switching device based on, at least in part, information received from the zero cross detector and the current and/or voltage detector.
