Abstract :
This paper mathematically models and analyses various control methods for Dual-Active-Bridge (DAB) converters focusing in: its performance to reduce the reactive power to zero while keeping the load current without discontinuities for any range of operation; minimizing the number of PI feedback loops to a single one; the reduction of IRMS and ripple voltage; reduction of losses, altogether compared to the conventional SPSC method. After comparations a novel control scheme using a single PI feedback-loop for abating reactive power is proposed. The simulation, mathematical model of the converter and the experimental results obtained from the laboratory-scale version of the DAB controller shows the performance of the proposal and its relative advantages.
