    • PROBLEM TO BE SOLVED: To solve a problem, wherein since the AC output generated by a permanent magnet type generator is a delay current, the gap magnetic flux of the permanent magnet type generator is reduced in magnetism, and accordingly, an internal induction voltage is lowered, in a distributed power supply generating set that uses the permanent magnet type generator having a variety of windings for acquiring a maximum output by wind force or the like, without using PWM converter. SOLUTION: This main circuit of a distributed power supply generating set is characterized in that the AC output of the permanent magnet type generator that is constituted of a plurality of the windings that generate different induction voltage effective values is rectified by an individual rectifier; a series capacitor is connected between an AC output terminal of the winding that generates a high induction voltage effective value among the plurality of windings, and the individual rectifier; and a series impedance between the capacitor and the permanent magnet type generator is set to be capacitive, in a range of the number of rated revolutions of the permanent magnet type generator.
