LITTLE KNOWN FACTS ABOUT VFD PANEL.

But, if we lessen the frequency to 30Hz, then we have to also decrease the voltage to 240V as a way to preserve the V/Hz ratio. How are we going to decrease the voltage if the sole voltage We've got is 650VDC?We can eliminate the AC ripple about the DC bus by adding a capacitor. A capacitor operates in an identical vogue to your reservoir or accumu
