Bidirectional Modular Multilevel DC/DC Converter with Wide Range of Control

Abstract

In this paper we describe about the utilization of braking energy during regenerative braking operation by using different cascaded multilevel topologies by interfacing of the super capacitor to dc bus in the regenerative applications. Energy storage plays an important role in the high power application. Super capacitors are chosen because they have high density, efficiency and long life cycles. The modular multilevel dc/dc converter (MMC) is used to reduce voltage and increase frequency across the inductor in order to reduce the weight and size of the inductor with phase shifting modulation. The circuit is used as a bi-directional power source and converter. The super capacitors are used for voltage balancing for output current control. The proposed system is plays an important role in hybrid and electric vehicle applications
