Özet
Multilevel inverters have been widely used in the power applications to get low total harmonic distortion (THD) in medium or high voltage levels. There have been several techniques that can be applied to multilevel inverter so as to get low THD in the output voltage. Selective Harmonic Elimination (SHE) technique is one of these techniques and also has an extensive field of applications in power electronics. It is also an alternative to usual PWM techniques and includes nonlinear equations of stepped voltage waveform. In addition, SHE technique offers to control effective value of output voltage. In this paper, multilevel inverter with reduced number of switches which enables a reduction in the system cost has been proposed, and solution of nonlinear SHE equations have been optimized by Genetic Algorithm (GA) software. The results of simulation and analysis have clearly demonstrated that proposed GA based SHE technique can eliminate desired harmonic order.
