Abstract
PURPOSE:To prevent withstand voltage drop as well as dV/dt misignition, by constituting a primary and a secondary thyristors into different components and by placing them on a common cooling radiator. CONSTITUTION:An anode and a cathode of a primary thyristor 11 are connected through copper plates or the like to radiators 22 and 21 respectively, and a secondary thyristor 31 is fixed through a copper plate or the like to the radiator 22. A gate of the primary thyristor 11 and a cathode of the secondary thyristor 31 are connected by a lead wire 4, whereas a light guide 5 is connected with the cathode of the secondary thyristor 31, and then electric ignition signals are given to the primary thyristor 11. By so doing, required power for the secondary thyristor, comparing to that of the primary thyristor, is small enough so that junction temperature of the secondary thyristor is maintained 10 deg.C or less than junction temperature of the primary thyristor, thereby withstand voltage drop and dV/dt misignition of the element can be prevented.
