ABSTRACT:
In an electric power generating apparatus for dispersed power supply using a permanent magnet type electric power generator having many kinds of windings in order to obtain the maximum output by force of wind without using PWM converter, there is a problem that gap magnetic flux of the permanent magnet type electric power generator is demagnetized to decrease the internal induced voltage because alternating current output of the permanent magnet type electric power generator is lagging current. In an electric power generating apparatus for dispersed power supply including a permanent magnet type electric power generator having a plurality of windings inducing different effective values of induced voltages and individual rectifiers for rectifying alternating current outputs of the permanent magnet type electric power generator, a capacitor is connected in series between the individual rectifier and the alternating current output terminal of the winding inducing higher effective value of induced voltage among the plurality of windings in a manner that serial impedances of the capacitor and the permanent magnet type electric power generator become capacitive within the range of rated rotational speed of said permanent magnet type electric power generator.
