In the lighting field, LED light-emitting products are attracting the world's attention, LED as a new type of green lighting products, is the future trend of development. LED drive power supply as the core technology of LED lighting, power factor and efficiency has been low, become an obstacle to promote the application of LED lighting engineering major bottleneck. Based on Sepic topology and power factor correction with LED drive power can not only effectively improve the power factor and efficiency, reduce reactive loss, while for saving energy and reducing consumption, reducing costs also has very important significance.
