Study of Single Pulse Width Modulated Inverter and Sinusoidal Pulse Width Modulated Inverter using Low Pass Filter and Comparison of the Respective Total Harmonic Distortion of Output Voltages using FFT Technique

Abstract- This paper highlights the problems associated with single pulse width modulation, the most important being high harmonic content in output voltage. A comparative study with Sinusoidal Pulse Width Modulation Technique is done highlighting the reduction in Total Harmonic Distortion of the output voltage waveform. Keywords- Sinusoidal Pulse Width Modulation(SPWM), Total Harmonic Distortion(THD), Fast Fourier Transform(FFT) Analysis, Carrier Wave Frequency, Modulating Index(MI), Low Pass Filter(LPF). […]
