| Abstract |
Approaching the desired output voltage curve of a power electronic inverter by pulse width modulation the pulse pattern of every individual sampling step may be investigated off-line deducing algorithms for optimized modulation procedure. For single phase inverters symmetrical switching points are best. ln three phase inverters it is possible to add a freely set zero sequence component to the desired voltage without changing the modulation factor but varying the harmonics produced by pulse width modulation. This degree of freedom may be used for optimization of pulse pattern in each sampling interval. This method is demonstrated and investigated, Theoretical and practical results are presented. |
