Description
Summary:In this paper, a novel technique using proportional current feedback is proposed to improve the dynamic response of digital voltage mode PWM DC/DC converters. Due to the simplified structure, circuits can be implemented without microprocessors, DSPs, and external ADCs. As a result, it is possible to integrate the whole controller on a single chip. System circuit model is simulated using MATLAB. The results showed satisfactory performance to meet power requirements of current microprocessors.
