Abstract:
In this paper, for Selective Harmonic Elimination (SHE) in cascaded multi-level inverters and reaching optimal switching angles to eliminate low-level harmonics in output waveform, Imperialist Competition Algorithm (ICA) is used. ICA is implemented on 7-level and 11-level inverters so that optimal switching angles are achieved by solving formed non-linear equations. ICA is a general searching strategy with socio-political stimulus which was introduced to solve different optimization problems and has more accuracy and faster convergence compared to similar algorithms. Results obtained from ICA will be compared with GA and this method is superior in achieving general minimum amount and having more convergence rate. To investigate analyses and simulation results, an experimental sample of inverter in an empirical study will be presented, as well.
