Claims

[Scope of utility model registration request]

An internal combustion engine, an alternator driven by the internal combustion engine and having a field coil, a storage battery charged by the cleaning output of the alternator, and a starter motor connected with electricity from the storage battery to start the internal combustion engine. and a voltage regulator that controls the voltage generated by the alternator to a predetermined value by controlling the field current flowing through the field coil of the alternator, and a protection device that protects the starter electric machine from damage. In the internal combustion power supply device for a vehicle, the protection device includes a pulse generation circuit that detects the generated output of the alternator and detects the rotational speed of the alternator, and a pulse signal output from the pulse generation circuit. an operating timer circuit; a voltage comparison circuit that compares the output of the timer circuit with the output of the pulse generation circuit; an amplifier circuit that controls the starting motor based on the output of the voltage comparison circuit; Detecting and holding the output, and ensuring that the voltage generated by the alternator is a predetermined value;
When the value falls below the above value, the above holding effect is canceled.
A vehicle comprising: a self-holding circuit;
Internal combustion power supply device for use.
