Investigation of PWM using Sinusoidal Waveform as a Career Signal for Reduction of Magnitude of Specified Harmonics
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 5, Issue 11
Abstract
Many researchers have been done on PWM switching methods for finding better ways to supply the loads, which have lower harmonics in outputs. Applying of triangular career signal in SPWM is a common way. In this paper, the novel technique of using of sinusoidal career signal has been presented. To validate the proposed techniques, simulation studies have been carried out with SABER software. Results have been compared with conventional SPWM. The results show that in some harmonics this new technique is better than SPWM method. Therefore this new technique can be used for decrease some specified harmonics. Moreover, simplifying of solving the related mathematical equations is another advantage of this new method, because only sinusoidal equations are appeared and triangular signal is not used.
