<p>PURPOSE:To provide an output current controller for the generator in a vehicle in which the deficiency of battery charging current can be restricted by restricting the duty factor at the time of starting an engine and relaxing the restriction of duty factor during rotation of the engine. CONSTITUTION:Upon application of an IG voltage, a generating voltage regulating means 28 turns a switch 34 ON/OFF based on the battery voltage thus feeding or interrupting the exciting current. At the rising time of generated voltage, a duty factor limiting means 29 limits the duty factor of the switch 34 to restrain power generation. Means 15 for relaxing the restriction of duty factor detects the rising rate of generated voltage after application of IG voltage and when the rising rate is high, a decision is made that the restriction can be relaxed thus relaxing the restriction. When the rising rate is low, the engine is starting and thereby the restriction is not relaxed.</p> |
