Abstract

A primary side controlled offline Flyback LED driver is an very attractive LED driver solution due to its low component cost and high efficiency. However, as any other single-stage LED driver, it produce significant low frequency ripple current. In this paper, an innovative primary side controlled Flyback LED driver with low frequency ripple cancellation has been proposed. The low frequency ripple current has been greatly reduced while maintaining multiple primary side controlled LED driver advantages, such as high efficiency, low component cost, and low design complexity. A 35W, 50V-0.7A universal input experimental prototype has been built to verify the proposed technology.
