Abstract
PURPOSE: To detect a thyristor failure using the voltage appearing between the neutral point of a low voltage AC power supply and the DC terminal of a bridge circuit by applying the AC which is lower than the power voltage of a power converter to the AC terminal of a thyristor bridge circuit.
