Abstract

To eliminate the losses in the power electronic circuits, we have to include some different methods like Modular multilevel inverter. The design of a control circuit for a solar fed modular multilevel inverter to reduce the number of semiconductor switches is presented in this study. The design includes a binary mode of operation with PWM Techniques. In binary mode, 2Ns +1 − 1 output voltage levels are obtained where Ns is the number of individual inverters. MMC intends design in both control and power circuits to provide corresponding output voltage levels by appropriate switching sequences. Hence to obtain a 15-level inverter, the conventional method requires 28 switches and in binary mode 12 switches are needed but in the proposed system only 8 switches are employed to achieve 31 levels with low THD and high power quality. The advantage of this design is the reduction of total harmonic distortion.
