This paper introduces a control scheme to improve efficiency as well as both the input and output current ripples of multiphase interleaved buck converter (IBC), which is suitable for applications that require a wide range of output voltage. The number of phases is dynamically changed throughout the entire range of the output voltage in order to obtain the optimum efficiency and the lowest output ripple possible. The paper demonstrates the proposed approach on a single converter of a fast DC charger module which usually consists of multiple converters connected in input-parallel output parallel (IPOP) configuration. Simulation results show that the proposed technique significantly reduces the output current ripple when compared with the conventional phase-shedding technique while maintaining satisfactory high efficiency across the entire range of the output voltage.
