5 EASY FACTS ABOUT VFD CONTROL PANEL DESCRIBED

The DC voltage is then synthesized back into 3-period AC output voltage by way of a number of switches or transistors. The commonest ones in use now are insulated gate bipolar transistors (IGBT). These rapid switching IGBTs are operated rapidly to make a sq. wave using pulse width modulation (PWM).A variable frequency generate (VFD) is a motor co
