基于Boost-PFC整流器和电流源电荷泵的单级LED驱动变换器

This article presents a single-stage converter based on the boost-PFC (power factor correction) and charge-pump circuits configured as a current source. The integration between the input and the dc-link stages is performed by an output stage consisting of a full wave rectifier associated to a capacitive filter, an LED array, and a resonant series inductor. The charge-pump capacitors operate in ord...
