摘要：

A low part count, efficient quasi-resonant light-emitting diode driver is proposed. The proposed driver relies on a capacitive safety isolation barrier, which eliminates the need for a bulky isolation transformer; thus, the footprint area can be reduced. Operation frequencies of 100-350 kHz further contribute to miniaturisation of the proposed driver. The feasibility of the proposed topology is verified by simulation and experimental results.
