摘要:
A ballast converter with a power factor and crest factor correction to be connected to an input source for providing an input voltage. The ballast converter includes a rectifier, a power converter, and a valley fill circuit, wherein the power converter recharges the valley fill circuit for energy storage storing energy while the value of the first voltage is larger than a predetermined value, the valley fill circuit provides the first voltage with a supplementary energy while the value of the first voltage is lower than the predetermined value, and the predetermined value is adjustable by the valley fill converter circuit.
