Abstract

En vekselretter blir drevet for å eliminere susing under styring av hastigheten til en induk- sjonsmotor som benytter en vekselretter med variabel frekvens. Spenningen blir tilpasset den valgte frekvens for å unngå slik susing, og regulering av spenningen blir utført ved å regulere avstanden mellom pulsene som mates ut av styreenheten til styreelektrodene på de MOSFET-transistorer eller IGBT-transistorer som danner vekselretterens armer.
