された状態になる。Describing the case where generator 1 is generating power normally,
When the output voltage of the generator 1 exceeds a predetermined value, the voltage between B (base) and E (emitter) of the first transistor 9 turns ON.
The voltage becomes higher than that, and the first transistor 9 is turned on. Then, the second transistor 10 is turned off, and the resistors 20 and 21 are connected between BE and E of the third transistor 11.

Via the Zener diode 14, the B-El'B'I voltage of the third transistor 11 becomes higher than the ON voltage and becomes conductive. Then, the fourth transistor 12 is cut off, no current flows from the battery 5 to the rotor winding 3, and the generator 1 stops generating electricity.

なる。Next, if the state of charge of the battery 5 is good and the load on the battery is relatively small or there is no load, even if the generator 1 stops generating electricity, the voltage of the battery 5 will drop below the control voltage. Since the voltage does not drop immediately, the period during which the generator 1 stops generating electricity becomes longer, and as a result, the output voltage of the generator 1 decreases. When the output voltage of the generator 1 becomes less than a predetermined value, the first transistor 9 is turned off and the second transistor 1o is turned on.

Since the output voltage of the generator l is set to operate at a lower value (third predetermined value) than the predetermined value that turns on the transistor 9, and the output voltage of the generator l is not lowered by the predetermined value, the power generation Although the machine 1 is rotating and operating normally, the warning light drive circuit 40 is activated and the charging warning light 7 does not turn on instantaneously.
