Abstract :
The principle of vector control was investigated for a three-switch delta inverter. The vector pulse width modulation (PWM) techniques, both in the deterministic and random versions, were compared with the traditional sinusoidal PWM strategy. The achieved enhancement of the operation of the delta inverter has been documented by results of computer simulations and an experimental investigation of a laboratory model. The study confirmed the superiority of the vector PWM techniques over the sinusoidal PWM strategy for a delta inverter. However, the improvement in the operating characteristics of the inverter is not as significant as that witnessed in bridge inverters. The random version of the vector PWM technique results in radically better harmonic profiles of the output voltage and current than those with the deterministic version
