In this paper, the authors investigate the performance of various voltage control signal techniques for single phase PWM inverter. These techniques include single pulse width modulation, multiple pulse width modulation, sinusoidal pulse width modulation, modified sinusoidal pulse width modulation and phase displacement control. The performance of these carrier schemes are evaluated in terms of harmonic factor, total harmonic distortion and lowest order harmonic through simulation runs in MATALAB/Simulink. The technique with better harmonic spectrum is then implemented using an inexpensive and readily available AT89S52 microcontroller which generates the gating signals including dead time for switching devices comprising the inverter.
