摘要： PROBLEM TO BE SOLVED: To provide a current detecting circuit capable of detecting a current flowing through a driven object with high accuracy without using a temperature compensating component.
SOLUTION: By turning an NMOS 11 on and off, a driving current flowing through a solenoid 15 flows through a converter circuit 16. The converter circuit 16 outputs a voltage corresponding to the driving current. An amplifier circuit 17 outputs a current detection result which amplifies an output voltage from the converter circuit 16. Resistor elements 16
1 -16
n constituting the converter circuit 16 are closely formed on a common semiconductor substrate 100 together with elements constituting the amplifier circuit 17. Therefore, even when the driving current causes the converter circuit 16 to generate heat, the amplifier circuit 17 exhibits nearly the same temperature. Thereby, current detection can be implemented with high precision without using the temperature compensating components.

摘要： PROBLEM TO BE SOLVED: To simplify the circuit configuration of the power supply-controlling device of a generator, and at the same time to inhibit sudden change in the driving torque of the generator caused by drastic fluctuation in a load. SOLUTION: When an electric load (5) becomes an overload, a MOS-FET (309) is turned on and off according to the output signals of clock and retriggerable clock pulse generators (306) and (307), respectively, and the on period of the MOS-FET (309) is accumulated and extended for each cycle of operation by the time difference (t2-t1) between the first and second, thus gradually bringing the level of the output voltage of an AC generator (1) closer to that of a reference voltage (VR), and hence inhibiting the sudden change in the driving torque of the AC generator (1) caused by the drastic change in the electric load (5). Each of a comparator (304), the clock and retriggerable clock pulse generators (306) and (307), and a driving control circuit (311) can be put together into a one-chip microcomputer by program control, thus simplifying the circuit configuration of the entire controlling device.
