Abstract

Performance of hybrid inverter with less number of components is presented in this paper. When compared to diode clamped, flying capacitors, and cascaded H-bridge multilevel inverters, the hybrid inverter requires fewer components, fewer carrier signals and gate drives. Therefore, the overall cost and complexity are greatly reduced particularly as the output voltage level increases. Implementation of single phase seven-level, ninelevel and eleven-level hybrid inverter have been performed using sinusoidal pulse width modulation (SPWM) techniques i.e., phase disposition (PD) and alternate phase opposition disposition (APOD). The total harmonic distortion (THD) is evaluated for various modulation indices using MATLAB/SIMULINK.

Keywords: sinusoidal pulse width modulation; hybrid inverter; alternate phase opposition disposition; phase disposition; total harmonic distortion;
