摘要：

With the wide application of light emitting diode (LED); the study of high efficiency, low cost, high power factor and high reliability of LED drive power supply has become a hot research topic. In this paper, a 60W high power factor LED driver power supply with cascade topology is designed. The boundary conduction mode (BCM) is used for the AC -DC part with active power factor correction, and the quasi -resonant work mode is used for DC -DC flyback converter. The working principle is 'analyzed and the experimental platfonn is built; experimental results show that the LED dnver with the proposed method has higher power factor, lower harmonic current distortion and higher conversion efficiency in the whole input voltage range.
