RUMORED BUZZ ON VFD

Let's believe which the travel is working with a 480V electricity method. The 480V ranking is “rms” or root-imply-squared. The peaks with a 480V program are 679V. As you could see, the VFD dc bus provides a dc voltage using an AC ripple. The voltage operates concerning somewhere around 580V and 680V.Considering that the capacitors are usually n
