Abstract

PURPOSE:To improve assembling workability and to achieve stable operation, by thermally coupling insulating type small signal transistors with respective main drive transistors. CONSTITUTION:Switching transistors(Tr) 3a-3b thermally coupled with small signal Tr 11a-11b are arranged as main drive transistors. A voltage applying circuit 12 containing Tr 3a-3b is connected to the gate of SCR 9. Upon occurrence of abnormality in a load, i.e. a discharge lamp 7, Tr 3a-3b are heated to increase the temperature of the small signal Tr 11a-11b. Consequently, a divided voltage is applied onto the gate of SCR 9 when the small signal transistor Tr 11b is turned ON, and the opposite ends of the winding 4b of a current transformer are shortcircuited so as to stop oscillation.
