  • IDF-correction-based PWM algorithm for a three-phase AC-DC buck converter
    Milanovič, Miro ; Šlibar, Primož
    This paper presents a pulsewidth modulation (PWM) algorithm for a three-phase ac-dc rectifier, where the third and fifth harmonics are indicated in the input phase voltages. A mathematical analysis, ... which includes this voltage harmonic's components, shows that the unity input displacement factor (IDF) can be reached by appropriate evaluation of duty-cycle functions. A PWM algorithm is proposed based on this developed theoretical achievement. This approach enables current sensorless unity IDF rectification. The PWM algorithmis investigated theoretically and verified by simulations and experiment.
