A SECRET WEAPON FOR VFD PANEL

But, if we reduce the frequency to 30Hz, then we have to also decrease the voltage to 240V so that you can manage the V/Hz ratio. How are we going to decrease the voltage if the one voltage We've is 650VDC?Consequently, the voltage on the DC bus gets “around” 650VDC. The particular voltage will count on the voltage amount of the AC line feeding
