Investigation of PWM using Inductor-Switch for each Leg of Inverter for Reduction of Total Harmonic Distortion
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2013, Vol 5, Issue 10
Abstract
Many researchers have been done on PWM switching methods for finding better schemes to supply the loads, which have lower harmonics in outputs. In SPWM, semiconductor switches are directly connected to rectified voltage in output of rectifier. In this paper, the novel technique of using Inductor-Switch for each Leg of Inverter has been presented. In this technique an inductor is used between each semiconductor switch and rectified voltage of rectifier’s output. To validate the proposed technique, simulation studies have been carried out with SABER software. Results have been compared with conventional SPWM. The results confirm that this novel technique causes lower total harmonic distortion and lower acoustic noise. Therefore, this new technique can be used to decrease harmonics and total harmonic distortion in voltages and currents of output.
