This is a prototype on a Variable Frequeny Driver or VFD. With this circuit we would control the frequency of high AC voltage and by that the speed of induction AC motors. Since we work with high voltage, is a dangerous circuit so be careful. The idea is to turn 230V AC voltage to DC vo... view more
