Abstract
Recently the use of high power Voltage Source Inverter is increased but the problem of harmonic and switching losses in inverter are also increased because of the use of power electronic switches, which are used for fast and efficient operation. In this paper, for eliminating the harmonics presented in H Bridge inverter during switching operation of the power electronic switches the Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) Technique is used. For H-Bridge operation specific switching angles are calculated by solving nonlinear equation using Newton Raphson method. The result of H-bridge single phase inverter are implemented on hardware with and without SHEPWM technique for eliminated specific 3rd,5th,7th,9th,11th,13th voltage harmonics are obtained. Comparison of harmonic analysis of H bridge inverter with and without SHEPWM technique is done. In this paper Modulation index (m) is varied to control output voltage amplitude and the results are observed for maximum modulation index.
