RUMORED BUZZ ON VFD CONTROL PANEL

Let's assume which the drive is functioning on a 480V power process. The 480V rating is “rms” or root-necessarily mean-squared. The peaks on the 480V program are 679V. As it is possible to see, the VFD dc bus includes a dc voltage with the AC ripple. The voltage operates concerning about 580V and 680V.The facility from the DC bus is thereafter
