Abstract

PURPOSE:To facilitate the current transfer from an auxiliary GTO thyristor to a main GTO thyristor by a method wherein a circuit is composed by providing a bias resistor across the terminals of the auxiliary GTO thyristor and the main GTO thyristor. CONSTITUTION:The gate terminal of a main GTO thyristor 1 and the anode electrode of an auxiliary GTO thyristor 2 are directly connected and a bias resistor 9 is provided across both anodes of the thyristors 1 and 2. In this composition, no factor generating the potential difference between the gate and cathode of the thyristor 2 exists against the gate current in the thyristor 1 caused by the firing of the thyristor 2 and enough firing current can be flowed even if the voltage of a gate power supply 4 decreases and damage to the thyristor 2 will be eliminated.
