A Modified Sinusoidal Pulse Width Modulation (SPWM) for a Full Digital Power Factor Correction
The harmonic analysis results from the MSPWM method are shown through software simulation. By using proposed the proposed MSPWM with a fixed switching frequency, a good sine current with very low harmonic distortion can be obtained. Furthermore, since the proposed method does not need to sense a line current or voltage, it can be implemented by using a low speed and low priced conventional microcontroller (FMS7401).
