碩士 === 國立高雄海洋科技大學 === 微電子工程研究所 === 101 === This paper discusses the development of bridgeless boost circuit rectifier based LED driver with the bridgeless boost rectifier is composed of two power electronic switches with common ground. The power electronic switches are controlled by pulse width modulation (PWM). Accordingly, the input current of bridgeless rectifier is sinusoidal and in phase with input voltage, and it performs the unity power factor. For verifying the driver circuit, the prototype is developed. The experimental results show. that the proposed bridgeless boost rectifier has the expected performance.
