| Abstract |
In static power conversion, some command parameters act directly on the operating point of the power-supply-converter-load system and they allow the fundamental terms control (amplitude, frequency, phase). The others have a minimum influence on the operating point, but they allow the harmonic spectrum control. Particularly, using the well known PWM inverter structure, the authors show its versatility and make a review of all its applications. At first, the PWM inverter in DC/AC conversion, with fundamental voltage control, harmonic reduction, non linear load feeding. Then, the PWM inverter in AC/DC conversion, acting as a rectifier with sinusoidal input currents, power factor control, VAR and/or harmonic compensation. Lastly, some experimental results are given and the AC/AC conversion is examined. |
