Abstract

A single-stage LED driver usually produces a significant twice line frequency ripple current when a high power factor is achieved. The ripple current further produces a flicker through LEDs. In this paper, an energy channeling single-stage LED driver is proposed to achieve flicker-free LED driving while maintaining high power factor correction. It also achieves true single stage power conversion and low component cost. A 8.5W, 50V/0.17A Buck-Boost experimental prototype has been built and tested to verify the proposed method.
