PURPOSE:To prevent temporary decreasing of the number of revolutions of an engine, by providing an engine control means which performs correction of an increase in a suction amount of an engine and a reference value regulating means which sets the reference value of a field current control means to an allowable limit value. CONSTITUTION:An alternator 16, which is a power supply source to a load, is provided. A load correcting circuit 24 determines a correction amount for a suction amount of an engine to feed it to a control circuit 28 for the number of revolutions of an engine. A reference value regulating means 33, which is actuated during detection of the load input of a load input detecting means 20 and sets the reference value of control motion of a field current-in-given time control means 31 to an allowable limit value of a decrease in the number of revolutions of an engine, is provided. This prevents the occurrence of a production lag in a load during input of an electric load, and enables prevention of a temporary decrease in the number of revolutions of an engine. |
