A REVIEW OF VFD CONTROL PANEL

But, if we decrease the frequency to 30Hz, then we must also decrease the voltage to 240V to be able to manage the V/Hz ratio. How are we planning to lessen the voltage if the only voltage Now we have is 650VDC?This is known as Pulse Width Modulation or PWM. Visualize that we could control the tension in a drinking water line by turning the valve o
