御する。In this operation, the output of the generator 1 is first controlled to a constant voltage DC by a battery charging circuit b and supplied to the battery 20 and the DC load 21. On the other hand, the tap output of the generator 1 is rectified by the rectifier 4 of the detection circuit a and then divided by the detection resistors 5 and 7 and smoothed by the capacitor 6. If the output of the generator 1 rises due to the rotation fluctuation of the generator 1, the smoothed voltage of the capacitor 6 rises, the Zener diode 9 conducts, and the transistor 10 turns on. Here, when the output of the generator 1 goes into a negative cycle, the SCR through which the gate current of the SCR flows via the rectifier 4, the transistor 10, and the resistor 12 turns on, and the generator 1
Output is short-circuited and the rise of the output voltage is suppressed to control to a constant voltage.
この種の電圧調整器は安価な二輪車に積載されるため
ユーザーからのコストダウン要求が非常に強いが従来回

ある。2, the output of the generator 1 is charged to the capacitor 6 after being rectified by the rectifier 4 via the detection resistor 5 as in the conventional circuit. The charging voltage at this time is determined by the voltage dividing ratio of the resistors 5 and 6, and is the same voltage as the conventional one because only the detection resistor 5 is moved to the AC side. Here, attention is paid to the point A voltage at the time of the negative cycle of the generator 1 (based on the SCR cathode). When the output of the generator 1 is in a negative cycle, the forward voltage [Vd] of the diode 4a is generated at the negative electrode of the capacitor 6 by the current of the resistor → diode 4d → capacitor 6 → diode 4a. Vd] + the voltage of the capacitor 6. Here, when the output voltage of the generator 1 rises, the point A voltage rises and the Zener diode 9 becomes conductive, the SCR 13 turns on, and thereafter the output of the generator 1 is short-circuited and voltage control is exactly the same as in the conventional case. .
