Abstract

PURPOSE: To make 100 % the using rate of each element of pulse amplifying circuit by providing one power switch to each thyristor bridge and by using in common the rectifying device of pulse amplifying circuit, auxiliary thyristor, and condenser at both normal and reverse operations.
CONSTITUTION: A gate signal is supplied to the thyristor 11 to 26 of the anti-parallel thyristor converters SCRA and SCRB. At the time of normal operating acceleration, the switch SWB becomes OFF, the switch SWA becomes ON, and the gate signal to the thyristor converter SCRB is locked. The charge charged into the condenser 1C is discharged through the condenser 1C-the switch 1SW-the switch SWA-the pulse transformer 11PT and the pulse induced in the secondary winding of the pulse transformer is supplied to the gate of the thyristor 11 of the thyristor converter SCRA. Gate signal is likewise supplied to the other thyristors. Then, at the time of reverse operating accelaration, the switch SWA becomes OFF, the swtich SWB becomes ON, and in the same way as the aforegoing, gate signal is supplied from the secondary winding of the pulse transformers 21PT to 26PT to the gate of the thyristors 21 to 26 of the thyristor converter SCRB.
