VFD - AN OVERVIEW

Let's think the travel is working on the 480V energy process. The 480V score is “rms” or root-indicate-squared. The peaks with a 480V system are 679V. As you may see, the VFD dc bus has a dc voltage with an AC ripple. The voltage operates concerning around 580V and 680V.The IGBTs right here act like switches that when quickly switched on and of
