THD Minimization under Low Switching Frequency for Superior Two Level Three Phase Inverter Performance

The total number of switching pulses permitted in one-quarter the fundamental-cycle an inverter is restricted due to restrictions losses high-power devices. elimination major low-order dominating harmonics using SHEPWM (Selective Harmonic Elimination) suggested this research paper. positive or negative voltage transition at instant where fundamental has greatest slope distinguishes various types waveforms. Due loss limitations, two forms pole PWM waveforms i.e., type A, B, were studied lower pulse (P = 5). For a two-level three-phase inverter, ideal Pulse Width Modulated (PWM) waveform developed for whole modulation index range terms least harmonic distortion (THD). MATLAB simulation and practical experiments are performed support theoretical analysis results.
