Main Circuit of Generator for Distributed Power Supply

A main circuit of an electric power generating apparatus for dispersed power supply comprising a permanent magnet type electric power generator driven by a windmill or waterwheel and having a plurality of windings inducing different effective values of induced voltages, alternating current outputs of said permanent magnet type electric power generator being rectified by individual rectifiers, and direct current outputs of said individual rectifiers being summed up in parallel to output to an external, wherein

• said plurality of windings comprises three kinds of windings,
• a reactor is connected in series between a first individual rectifier and an alternating current output terminal of the winding inducing a lowest effective value of induced voltage among said three kinds of windings,
• a second reactor is connected in series between a second individual rectifier and an alternating current output terminal of the winding inducing a second lowest effective value of induced voltage among said three kinds of windings, and
• a capacitor is connected in series between a third individual rectifier and an alternating current output terminal of the winding inducing a highest effective value of induced voltage among said three kinds of windings, in a manner that a sum of inductive impedance by internal inductance of the winding inducing the highest effective value of induced voltage among said plurality of windings and capacitive impedance by said capacitor becomes capacitive impedance within a range of rated rotational speed of said permanent magnet type electric power generator.
