In this paper, a nine-level series H-bridge multilevel inverter is introduced and switching techniques like equal phase (EP), half height (HH) methods are used. The conventional multilevel inverter requires more number of switches as the level of switching increases. The proposed nine-stage inverter is more advantageous as the circuit requires eight switches compared to nine-level conventional inverter which requires 16 switches to get multi-step output. The cost and the switching losses for the proposed circuit are reduced. The proposed nine-stage inverter is compared with conventional series multistage inverter, and the total harmonic distortion (THD) is also compared. The THD analysis is obtained using MATLAB tool.
