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

The DC voltage is then synthesized again into 3-stage AC output voltage by way of a number of switches or transistors. The commonest kinds in use today are insulated gate bipolar transistors (IGBT). These fast switching IGBTs are operated quickly to produce a square wave making use of pulse width modulation (PWM).Your tools will past longer and wil
