Abstract
This invention provides a control device for automobile battery-charging generators, adapted to supply a plurality of sets of specifications in a highly reliable and stable form by simple switching between electrical characteristics assigning and limiting functions so as to meet various needs of users. In accordance with a voltage of a battery B, a voltage control IC regulatorcontrols a field current flowing through a field winding FL. The voltage control IC regulatorhas a plurality of functions for assigning electrical characteristics limits or electrical characteristics beforehand. The voltage control IC regulatoralso has switch terminals SWand SWthat switch the plurality of functions that assign the electrical characteristics limits or the electrical characteristics. Electric potential levels of the switch terminals SWand SWcan be changed by cutting cutoff portions CPand CPof an intermediate terminalor leaving these cutoff portions connected. Thus, an effective or ineffective state of the functions that assign the electrical characteristics limits or the electrical characteristics can be switched.
