The DC voltage is then synthesized back into 3-stage AC output voltage by way of a series of switches or transistors. The most typical kinds in use right now are insulated gate bipolar transistors (IGBT). These fast switching IGBTs are operated swiftly to produce a sq. wave making use of pulse width modulation (PWM).This ordinarily would make the s
