CONSIDERATIONS TO KNOW ABOUT VFD CONTROL PANEL

But, if we reduce the frequency to 30Hz, then we must also lessen the voltage to 240V in an effort to keep the V/Hz ratio. How are we about to reduce the voltage if the only real voltage We now have is 650VDC?We can easily eliminate the AC ripple to the DC bus by including a capacitor. A capacitor operates in an analogous style to a reservoir or ac
