ABSTRACT Selective harmonic elimination technique is one of the extensively used methods for low thermal losses and high converter efficiency in medium and high voltage application. The nonlinear transcendental trigonometric SHE equations are highly nonlinear character in multilevel inverter; hence it is very difficult to obtain feasible solution at desired value of modulation index. This paper presents comparative analysis of NR method with random initial guess and new algorithm such as elitist teaching learning based optimization technique to solve SHE equation set at different values of modulation index. To confirm the proposed technique, a single phase 27 level Cascaded Multilevel Inverter has been considered and the developed algorithms are tested at different modulation index. MATLAB programming and SIMULINK model has been developed to validate the proposed optimization methods. A 5kW solar photo voltaic power plant has been designed and implemented with 27 level Cascaded Multilevel Inverter with the SHEPWM algorithm. |
