Abstract
Disclosed are a method and an apparatus of digital feedback based adaptive delay time control for a high efficiency active rectifier. According to the present invention, provided is an apparatus for digital feedback based adaptive delay time control, which adaptively compensates a driving delay of a switch by controlling a time of a delay circuit through a digital feedback-based compensation technique, and operate the switch at an appropriate timing in spite of changes in operation environments such as an input voltage and a load to increase the efficiency of an AC-DC rectifier.
