LITTLE KNOWN FACTS ABOUT VFD PANEL.

The DC voltage is then synthesized again into 3-phase AC output voltage via a series of switches or transistors. The most typical ones in use now are insulated gate bipolar transistors (IGBT). These speedy switching IGBTs are operated swiftly to create a sq. wave using pulse width modulation (PWM).Whenever we near one of many top rated switches fro
