Dc/Dc Converter Fed With Dc Motor Phase Shift Control Scheme for Modular Multilevel

Abstract

Dc-based distributions and dc-based micro grids are recognized as the promising answers for future brilliant smart grid because of their reasonable points of interest of adaptability for photovoltaic and fuel cells interface, without frequency stability, high change proficiency, and simple system control. Modular Multilevel converter is speaks to a rising topology with adaptable innovation and high voltage and force ability is conceivable. The (MMC) Modular multilevel converters depend on falling of half scaffold converter cells and combine of low switching frequency and low harmonic interface. They can be designed for high operating voltages without direct series connection of semiconductor element. By using the full bridge modules in series the high switch voltage stress in the primary side is reduced. The principle of the phase-shift-controlled three-level dc/dc converter, and the modular multilevel dc/dc converters, by integrating the full bridge converters and three-level flying capacitor circuit, are investigated in this paper. The proposed concept is implemented to control of DC motor using modular multilevel dc-dc converter using MATLAB/SIMULINK software
