Abstract : In this paper, a Cascaded H-bridge eleven level inverter is controlled with multicarrier phase disposition (PD) and Alternative Phase Opposition and Disposition (APOD) techniques. The THD variation in the inverter output voltage is observed from the simulation results. A PI control algorithm is implemented in LPC2148 Arm Processor. The validity of the proposed inverter is verified through MATLAB/SIMULINK programming environment and is implemented in a single phase 300 W prototype. The performance of the proposed method is compared with that of the conventional method. Based on the observation results obtained that Multicarrier Phase Disposition (PD) technique is found to perform better since it provides higher fundamental output voltage and lower total harmonic distortion.
