一致するように制御される。 In the power generation voltage control circuit 21, the current i is the current flowing through the resistor 211, the voltage V A is the divided voltage of the resistors 211 and 212 connected in series between the power supplies, and the voltage V A is the Zener voltage of the Zener diode 213. The generated voltage V B is controlled so as to be maintained constant at the sum of the base-emitter forward voltage of the transistor 214 and the base-emitter forward voltage of the transistor 214 . In other words, the generated voltage
When V B decreases and the voltage V A becomes lower than the Zener voltage, the transistor 215 is made conductive via the transistor 214, the rotor coil 11 of the generator 1 is excited, and the voltage V B increases. On the other hand, when the generated voltage V B increases and the voltage V A becomes higher than the Zener voltage, the transistor 215 becomes non-conductive, and the energization to the rotor coil 11 is stopped and the voltage decreases.
V B decreases. In this way, the voltage V A is kept constant, and the generated voltage V B is controlled to match the constant regulated voltage V R shown in the following equation ( 1 ), where the resistance value of the resistor 211 is R1. Ru.

is provided. A constant voltage V C is input to the negative input terminal of the comparator 221, and a selection signal generated from the selection signal generation circuit 3 is input to the positive input terminal.
O 1 is entered. When the voltage of the signal O 1 is lower than the voltage V C , the output of the comparator 221 is “0”
level, current flows into the comparator 221 from the connection point between the resistors 211 and 212, and as a result, the current i increases and the adjusted voltage V R
becomes higher. When the voltage of the signal O 1 is higher than the voltage V C , the output of the comparator 221 becomes “1” level, the flow of current to the comparator 221 is stopped, and the regulated voltage V R becomes low.

When the key switch 5 is not turned on, the signal S1 is at the "O" level, and therefore the voltage of the selection signal O1 is OV (region x in FIG. 2). As a result, the transistor 222 constituting the power switch circuit 222 in the selection circuit 22
a, 222b and the transistor 215 of the voltage control circuit 21 are all rendered non-conductive, no excitation current is supplied to the rotor coil 11, and power generation by the generator 1 is stopped.

述の如く、発電電圧VBは高い調整電圧VRに制御
される。 When the key switch 5 is turned on and the signal S2 is at the "0" level, the transistors 31 and 3
2 is non-conductive, so the voltage of selection signal 0 1 is the voltage obtained by dividing the battery voltage by resistors 33 and 34.
V 1 (y area in Figure 2). As a result, the transistors 222a and 222b become conductive, and the transistor 215 of the voltage control circuit 21 becomes conductive. When the engine starts and the rotation of the generator begins to increase, power generation begins. And the above voltage
Since V 1 is set lower than the voltage V C , the output of the comparator 221 is at the "0" level, and as described above, the generated voltage V B is controlled to the high regulation voltage VR .

せしめられて、スムーズな加速が可能となる。 On the other hand, when the engine load increases rapidly, such as when the vehicle suddenly accelerates, the signal S2 becomes "1" level. In this case, transistors 31 and 32
is conductive, and the resistor 35 is connected in parallel to the resistor 33. As a result, the voltage of the selection signal 01 becomes a voltage V2 higher than the voltage V1 . The voltage V 2 is set higher than the voltage V C , so the comparator 22
The output of 1 becomes the "1" level, and as mentioned above,
The generated voltage V B is now controlled to a lower regulation voltage VR . As a result, the amount of power generated by the generator 1 connected to the engine is reduced, the load on the engine is reduced, and smooth acceleration is possible.

て、配線の手間を大幅に削減したものである。 As described above, the regulator of the present invention is provided with a selection signal generation circuit on the vehicle body side that generates selection signals with different voltage levels, and on the other hand, the regulator part integrated with the generator has a selection signal generation circuit that generates selection signals with different voltage levels. A regulating voltage selection circuit that selects a predetermined regulating voltage according to the voltage is provided, making it possible to select multiple regulating voltages with a single selection signal, thereby greatly reducing the wiring effort. It is.
さらに、本実施例ではキースイツチを切つた場
合の発電停止も上記選択信号を介して行なつてい

3,224, a Zener diode 225 and a resistor 226 are provided, and the base of the transistor 224 is
Emitter forward voltage and Zener diode 225
