Abstract
PURPOSE:To reduce the capacity of a transistor by delaying the rise of a base voltage of the transistor connected in series with a fan motor when the motor is started. CONSTITUTION:Since the collector current of a transistor T1 is partly flowed through a condenser C1 and a resistor R3 to an earth when a fan switch SW is closed ON, the voltage at the point F does not become high until the condenser C1 is charged. Accordingly, the rises of the base voltages of transistors T2, T3 are delayed, and the collector currents of the transistors T2, T3 at the time of starting a fan motor M are reduced. In this manner, the transistors of small capacity can be used.
