Abstract

The modular multilevel converter topology (MMC) became potential converter topology for various high power applications. These are high voltage DC power transmission and other intertie connections of renewable energy sources to grid. The other application of MMC topology is variable speed drives, for controlling these variable speed drives a sine wave technique and square wave technique will be used. Particularly for high voltage direct current (HVDC) transmission applications, modular topology of voltage source converter gained attention because of its modularity, uniform modules connected in series or parallel. The other considerable advantage of MMC is their high efficiency because of low losses and the filtering requirements for harmonics are very less compared to other topologies. MMC gives increasing converter reliability and reduction of maintenance cost. This paper gives the simulation study of design of 50 Hz BTB system with 200 V and 10 kW. Two MMC-based converters connected back to back and control signals generated by using phase-shifted modulation. The main advantage of this DSC–MMC-based BTB intertie is the DC link capacitor and sensor for voltage is eliminated. The simulation study carried out for the DSC-based MMC for a 200 V, 10 kW, 50 Hz model with phase-shifted PWM. Simulation results of DSC–MMC-based BTB study and transient states are presented in this paper. Simulation carried by using MATLAB/Simulink software.
