The modular multilevel converters (MMC) are gaining popularity in grid-connected systems such as HVDC systems, renewable energy systems. This paper primarily focusses on high power application specially HVDC system. MMC has many advantages because of its high modularity, scalability and high power quality. Because of these features, this paper presents a MMC based HVDC system for large power exchange between two areas. The rotating d-q reference based vector control algorithm is used for the control and operation of above HVDC system. PWM plays a very major role for switching the power semiconductor devices of multi levels converter. Here PD-PWM has been used because of its simple structure and easy to implement for high number of levels. The proposed PD-PWM based HVDC system is verified through simulation and experiment. The simulation as well as experimental results are presented.
