Abstract

PURPOSE:To keep a gate current flowing through a by-pass, even if a cathode potential is fluctuated, and making unnecessary a high voltage operating circuit by connecting two SCRs in converse-parallel and setting up a by-pass by means of a transistor between the cathode gate and the anode gate.
