摘要
Abstract
Electrolytic capacitors would make the life of drivers decrease, and so removing the electrolytic capaci-tors can increase the life of drivers in the application of lighting under the mine. The boost-flyback single-stage power factor correction(PFC) converter works in different ways under different voltages, so different contol strategies can be used with the aim of eliminating electrolytic capacitors and correcting power factor. Simulation results are presented to verify the effectiveness of the improved control scheme.关键词
