The 12 pulse inverter is still widely used to combine a good sinusoidal waveform with a switching frequency of only 3 to 5 times the fundamental frequency of the inverter. Such a low switching rate has advantages in very high power inverters, in case of special requirements on low EMI or losses, or when the fundamental frequency is high.
This paper deals with VSI having pulse pattern control of the amplitude of the fundamental component of the output voltage . Some mathematical background in calculating the harmonics is given, as well as graphic optimisation of switching instants.
