| Popis: | In present world, multilevel inverters are attractive solution to meet medium voltage and high power levels. Control of multilevel inverters at low switching frequency can be done by solving nonlinear transcendental selective harmonic elimination equations set. In real time to control multilevel inverter with DC source solar panels using SHE technique is quite complex because solar panels may give slight variation of output voltage. Finding feasible switching angles is a challenging task, particularly dealing with unequal DC sources. In this paper, A rugged efficient Continuous Genetic Algorithm has to solve SHE equation set in control of three phase CHB 7-level inverter with equal and unequal dc sources and comparative analysis has been carried out. MATLAB programming and SIMULINK environment has been used %THD obtained at various values of modulation indices are complies with IEEE 519-1992 harmonic guidelines too. |
