DC microgrids (MGs) have many potential advantages compared with AC microgrids, which have attracted more and more attention in recent years. However, DC bus voltage control of these systems can be an important issue undergoing the power surplus or deficit. An energy buffer in the DC MG powered by the bidirectional DC/DC converter with energy storage systems (ESS) such as super capacitor were investigated...
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...
Parallel current mode control algorithm for DC-DC converters is introduced in this paper. This control strategy is composed of two parallel terms: voltage term and current term which is calculated based on the input voltage, inductor current and output voltage. The new duty cycle algorithm requires only one multiplication, one division and three additions in digital implementation. The simulation...
In this paper, an overview of recent advances in digital control of low to medium power DC/DC switching converters is presented. Traditionally, such DC/DC converters have been almost exclusively controlled through analog electronics methods. However, with the steadily decreasing cost of integrated circuits, the feasibility of digitally controlled DC/DC switching converters has increased significantly...
In this paper, a novel control method is introduced which refers to the concept of parallel current-mode control algorithm to obtain good dynamic performance for Buck converter undergoing a rapid load change and input voltage change. The duty cycle consisting of two terms: voltage term and current term is simple for implementation. Since there are only three additions and two multiplications. Besides,...
