For the traditional power supply of the non-continuous load Boost-Buck LED, when it has a high power factor, it will produce a significant low frequency ripple current. In this paper, a new type of LED driver power supply technology based on buck boost topology is proposed. The advantage of this technique is that the low frequency ripple current is greatly reduced without affecting the performance of the power factor and the advantages of high efficiency and low cost of the traditional boost buck LED driver are also preserved. We validate the performance of this new technology through a 30W and 50V-2A experimental prototype.
