IGNITION PULSE AMPLIFIER OF THYRISTOR

摘要: PURPOSE:To improve noise resisting properties at the output stages of this ignition pulse amplifier for simultaneously igniting a plurality thyristors, by mounting current limit circuit to stages. CONSTITUTION:The are formed means transistors TR2, TR3, and collector TR2 is connected power source line through consisting resistances R1, R2 condenser C2. The resistance R1 in circit limits currents range that TR3 become not less than holding thyristors Th. A series C2 makes up by-path curcuit which sufficient letting differential flow gates Th, rise portion TR3. Thus, false operation due noises induced from thyristor gate circuit, etc. can be prevented because base changed into shapes fit wave forms
