Abstract
A valley-fill circuit with active conduction angle control allows use of a single storage capacitor instead of two. The capacitor is charged to the maximum voltage of the AC cycle, which makes possible use of low-capacitance high-voltage low ESR capacitors, increases energy storage density and decreases circuit footprint. This makes it feasible to use ceramic capacitors, such as a multilayer ceramic (MLCC), polyethylene, polypropylene, or any suitable capacitor type in addition to electrolytic capacitors. This improves the operational longevity and reduces the footprint of the circuitry.
