Multilevel inverter is a power electronic device which is capable of providing desired AC output voltage using Multiple lower level DC voltages at input.Multilevel inverters have many advantages compared to Conventional inverters.It has low Harmonic Distortion and Electromagnetic Interference. Cascaded multilevel inverters synthesize a medium-voltage output based on a series connection of power cells which use standard low-voltage component configurations. This project presents a control strategies and modulation techniques used by these inverters. A PID controller is used to control the Capacitor Voltage.Quasi Switching Reduces the Electromagnetic Interference.The output voltage is the sum of the voltage that is generated by each bridge. The switching angles can be chosen in such a way that the total harmonic distortion is minimized.
