Abstract
PURPOSE:To display the stable performance even at the time of inverting polarity by connecting a resistance and a voltage dependent element to a collector and an emitter of a transistor and connecting a resistance comparator, an interruption circuit and a drive circuit. CONSTITUTION:The resistance 12 and the voltage dependent element 13 are connected to the transistor 11. Further, the comparator 14, the interruption circuit 15 and the drive circuit 16 are connected. By such constitution, the electromotive force being generated at the time of inverting the polarity is absorbed by the resistance 12 and the voltage dependent element 13 and the output of the transistor 11 is stopped by an action of the interruption circuit 15 with respect to the excessive electromotive force.
