PURPOSE:To compactly compose by distributing the positive and negative signals of the secondary side of a pulse transformer to thyristors connected in antiparallel with a diode circuit. CONSTITUTION:A fire signal is fed through a light guide 6 from a gate controller 7, amplified by an amplifier 5, and input to the primary side of a pulse transformer 4. The secondary side of the transformer 4 is divided to fire signals of thyristors 1, 2 by a diode 3. The thyristors 1, 2 are separately fired, and an AC voltage is applied between main circuits A-K. |
