Abstract
An output control device of a generation device including: a rectifier circuit that rectifies an output of an AC generator and applies the output across a battery; an inverter circuit provided between the battery and the generator; inverter control means for controlling the inverter circuit to convert a voltage across the battery into an AC control voltage and apply the voltage to an armature winding of the generator; and phase detection means for detecting a phase of a phase current flowing through the armature winding of the generator as a maximum output current phase, wherein the inverter control means is comprised to control a phase of the AC control voltage so as not to be delayed with respect to the maximum output current phase, and thus prevent a reduction in the output of the generator caused by an excessive delay of the phase of the AC control voltage.
