RUMORED BUZZ ON VFD PANEL

But, if we lessen the frequency to 30Hz, then we have to also decrease the voltage to 240V in an effort to sustain the V/Hz ratio. How are we gonna reduce the voltage if the only voltage We've got is 650VDC?Consequently, the voltage around the DC bus turns into “approximately” 650VDC. The particular voltage will depend upon the voltage volume o
