Abstract

For a conventional offline Buck-Boost LED driver, significant low frequency ripple current is produced when a high power factor has been achieved. In this paper, an innovative LED driver technology based on the Buck-Boost topology has been proposed. The featured configuration has greatly reduced the low frequency ripple current without compromising power factor performance. High efficiency and low component cost features have also been retained from conventional Buck-Boost LED driver. A 10W, 50V-0.2A experimental prototype has been constructed to verify the performance of the proposed technology.
