This paper presents a novel digital current-mode control strategy for dc–dc converters. In the proposed algorithm, the required duty cycle is calculated directly by two parallel terms. With some simple operations in digital implementation, the resultant control system achieves rapid and precise output voltage regulation under the input voltage and output load change. Moreover, the implementation of...
This paper presents a novel current mode controller for the synchronous rectifier Buck (SR-Buck) converter. In term of the discrete equation, the required duty cycle can be calculated directly with two parallel terms: the current term and the voltage term. Based on the analysis of the proposed algorithm, the small signal model of the closed-loop system is derived, thus a proportional and integral...
