“…Sinusoidal PWM is a method, which decides the ON and OFF period of the switches by comparing sinusoidal reference and triangular carrier. [5][6][7][8][9][10][11][12] Basically, the PWM methods can be classified into two sets, (i) By changing the reference waveform and (ii) Changing the carrier waveform. Discontinuous PWM is a method, which under first group whose reference shape is not pure sinusoidal which aids improve the fundamental and at the same time this will decrease the harmonic spreading effect of the inverter output.…”

The Harmonics control of any inverters can be decided by the PWM incorporated for the switches. In recent years the carrier and reference modification based research is going on the inverter field. This paper suggests that the alteration of carriers and references of the three phase voltage source inverter enhance the ability to decrease the harmonic content.This enhanced realization deals with the carrier and reference modification arrangement for three phase voltage source inverter through amalgamating the boosted reference and random triangular carrier. The boosted reference is the addition of sine reference with injection of 1/3rd of reference amplitude (3fs) in the middle portion of the reference wave. i.e., [Formula: see text] to [Formula: see text] and [Formula: see text] to [Formula: see text] . The proposed PWM scheme use two carriers, one is Triangle wave and another one is inverted Triangle wave. The process of selecting the winning carrier among the two triangle carriers is purely based on the LFSR technique. The spectral quality of the induction motor drives has improved by the random carriers. The simulation and experimental values are proving the validity of the PWM method. The PWMs are generated by using parallel processing enabled FPGA processor.
