HOW VFD CAN SAVE YOU TIME, STRESS, AND MONEY.

The DC voltage is then synthesized back into 3-period AC output voltage through a number of switches or transistors. The most typical kinds in use currently are insulated gate bipolar transistors (IGBT). These quick switching IGBTs are operated speedily to make a square wave making use of pulse width modulation (PWM).A VFD permits the operator to r
