摘要:
An output voltage controller for an AC vehicle generator is proposed. The output voltage controller can easily suppress variation in rectified output voltage due to a switching surge without using a slope generation circuit in a voltage adjustment circuit. An excitation circuit that excites a field coil 13 includes a circulation element 31, a semiconductor switch element 33, an inductor 35, and transient voltage absorption means 40. The circulation element 31 is connected in parallel to the field coil 13. The semiconductor switch element 33 is connected in series with the field coil 13 and turned on and off by a voltage adjustment circuit 60. The inductor 35 is connected in series with the field coil 13 and the semiconductor switch element 33. The transient voltage absorption means 40 absorbs a transient voltage generated in the inductor 35 in association with the switching of the semiconductor switch element 33 between ON and OFF.
