More Information
Summary:A control apparatus incorporated in a charging generator (1) for controlling interruption of an exciting current supplied to a field winding (4) of the charging generator comprises a power transistor (9) for intermittently interrupting the exciting current, a voltage detecting circuit (13,14,16) for controlling on-off of the power transistor depending on the voltage generated by the charging generator, a current detecting circuit (18, 20) for detecting an initial exciting current supplied to the field winding until the charging generator generates an output voltage high enough for starting its charging operation, and a circuit (11) for turning off the power transistor as soon as the value of the current detected by the current detecting circuit exceeds a predetermined setting.
