Abstract

PURPOSE: To obtain the weld quality substantially equal to that obtained from the power source of rectangular waveform, by carrying out the power supply to the transformer for the period of low voltage of the sine wave AC voltage, depending on the discharge from the previously charged capacitor.
CONSTITUTION: Capacitors 5, 5' and duo-directional type thyristors 6, 6' are inserted into the device for impressing on the primary side of the transformer 3, through two couples of thyristors 2, 2'. The reverse conductive thyristor 6 is ignited at the point A, and the power supply to the transformer 3 depending on the discharging current from the previously charged capacitor 5 is continued up to the point B. The power supply to the thyristor 2 is started at the point B, and the charge of the capacitor 5 and the power supply to the transformer 3 are carried out by the power source. Between points C and D, the power is supplied to the transformer 3 depending on the discharging current from the capacitor 5. At the point D, the forcible turn-off of the thyristor 6 is made; after that, the similar operation with the reverse current polarity is carried out, and voltages A', B', C' and D' are impressed on the transformer 3.
