Renewable Energy sources have had increasing penetration levels for grid connected Distribution Generation in the recent years. A suitable inverter with less switching frequency and improved efficiency is required. An alternative topology for Hybrid cascaded multilevel inverter with a reconfiguration technique to eliminate fault and a modified PWM technique is to reduce switching losses is developed. The proposed topology can reduce the number of required power switches than traditional MLI and increase efficiency.
