Abstract

The paper reviews the latest advance of the digital control technologies in DC-DC converters. The research on digital control is mainly focused on two areas. One is the methods to generate digital PWM (DPWM) signals to meet the output voltage accuracy requirement. Various dithering techniques have been developed to improve the output voltage resolution and at the same time to reduce the clock frequency requirement. The other is to develop new control methods that can utilize these advantages of the digital controller so as to improve the dynamic performance of the switching power converters. Several new digital control methods have been proposed and significant dynamic performance improvement has been achieved
