摘要： A system and method for a bridgeless power supply is disclosed. The bridgeless power supply includes a digital control module that controls a first switch, a second switch, and a transistor, thereby the bridgeless power supply rectifies an alternating current (AC) variable input voltage and regulates a direct current (DC) output voltage. The digital control module applies a first and second control signal to the first and second switches thereby rectifying and regulating the AC variable input voltage. Additionally, the digital control module provides a high frequency and constant duty cycle third control signal to the transistor in series with an output transformer of the bridgeless power supply device, to assure primary-to-secondary isolation.
