5 EASY FACTS ABOUT VFD CONTROL PANEL DESCRIBED

The DC voltage is then synthesized back again into 3-phase AC output voltage via a series of switches or transistors. The commonest kinds in use now are insulated gate bipolar transistors (IGBT). These rapidly switching IGBTs are operated rapidly to make a sq. wave making use of pulse width modulation (PWM).A VFD makes it possible for the operator
