THE 5-SECOND TRICK FOR VFD

But, if we decrease the frequency to 30Hz, then we have to also reduce the voltage to 240V in an effort to manage the V/Hz ratio. How are we likely to decrease the voltage if the one voltage Now we have is 650VDC?We can eradicate the AC ripple about the DC bus by including a capacitor. A capacitor operates in a similar manner to a reservoir or accu
