The Importance of renewable energy sources increasing day to day world. We need converters for interfacing renewable energy sources to grid. This paper proposes 21-level multilevel inverter for interfacing renewable energy sources to grid. This proposed topology used 16 switches and four voltage sources. The proposed MLI improve output voltage level and reduce device count. Different PWM techniques used for generating switching angels. The advantage of this proposed MLI to reduce the circuit complexity and total harmonic distraction. And installation area. The proposed multilevel inverter implemented Matlab/Simulink software.
