Abstract
An LCD (liquid crystal display) power supply includes an AC to DC converter circuit, a transformer, a DC to AC converter, and a feedback circuit. The AC to DC converter circuit couples an AC power supply to generate a DC signal. The DC to AC converter couples the DC signal to a primary side of the transformer and alternates polarities thereof so that an AC signal is generated on a secondary side of the transformer to supply for a load. The feedback circuit receives a first feedback signal indicative of power being supplied to the load and modulates the DC signal generated by the AC to DC converter circuit according to the first feedback signal.
