Allow us to presume the generate is running over a 480V power method. The 480V ranking is “rms” or root-mean-squared. The peaks on a 480V technique are 679V. As you can see, the VFD dc bus features a dc voltage with the AC ripple. The voltage runs amongst somewhere around 580V and 680V. Click here for more info about VFD panelVFD stands for Var
