Multiple Switching Patterns for SHEPWM Inverters Using Differential Evolution Algorithms
International Journal of Power Electronics and Drive Systems (IJPEDS), 2011 An investigation on multiple patterns for both odd and even number of switching angles in a three-phase selective harmonic elimination pulse width modulation (SHEPWM) inverter is presented. The switching patterns are eand classified on the basis of the harmonic performance of the waveforms output from the inverter.
