Abstract

A simple, efficient, and low-cost quasi-resonant LED driver is presented. The proposed driver relies on capacitive safety isolation barrier and eliminates the need for a bulky isolation transformer. Thus, cost and footprint area can be reduced. This paper describes the topology and presents the theory of operation. Theoretical predictions are verified by simulation and experimental results.
