Abstract
PURPOSE: To increase the maximum regenerating power by providing semiconductor switches which connect a commutation helping circuit to the AC power supply terminals of a converter, and semiconductor switches for inverting commutation- capacitor voltage.
CONSTITUTION: An AC power supply 1 is connected to a load 5 by way of an AC- side reactor 2, a main thyristor bridge 3, and a reactor 4. A diode bridge 7 is connected to AC-side terminals a and b of the main bridge 3, and an overvoltage suppression capacitor 8 is connected to the DC side of the diode bridge 7. Furthermore, is provided a commutation helping circuit 6, wherein are connected a commutation capacitor 65 and a commutation reactor 66 which are connected in series with thyristors 61 and 62, and thyristors 63 and 64 for inverting the voltage of the commutation capacitor 65. Therefore, the effect of the AC-side reactance 2 can be eliminated, and the regenerating power from an inverter 10 can be increased.
