In this article, the authors compared the performance of the three-segment space vector PWM algorithm with the five segment space vector switching sequence in terms of the first three orders of the n-order integral voltage harmonics factors.Abstract:
The comparisons of the new offered optimum three-segment and the previously considered five-segment variants of the space vectors switching sequence are continued in values of the first three orders of the n-order integral voltage harmonics factors and in values of the first three orders of some unified indices, the so-called n-order aggregate switchings and integrated voltage harmonics factors. The corresponding dependencies on the amplitude modulation index are presented. The simulation results have proved the clear superiority of the new offered three-segment sequence in the main aggregate index values. The offered voltage source multilevel inverter space vector PWM algorithm of two delta voltages with the optimum three-segment vectors switching sequence variant can find industrial application due to its simplicity.read more
