<p><P>PROBLEM TO BE SOLVED: To solve the problem that a pinwheel is not triggered due to low wind speed or poor trigger performance of the pinwheel, relating to a power generating device for a distributed power supply which uses a permanent magnet type generator that includes multiple types of windings for obtaining a maximum output from wind power with no PWM converter. <P>SOLUTION: Relating to a main circuit of the power generating device for a distributed power supply, the permanent magnet type generator includes a plurality of windings which are driven by a pinwheel for generating varying induced voltage effective values. An AC output thereof is rectified with an individual rectifier through an individual reactor, and the DC outputs of respective rectifiers are added together and output to the outside. A tap is provided to the individual reactor connected to a winding having the largest number of turns among the plurality of windings. A contact device is provided which detects a rotational speed of the pinwheel, and shorts the tap of individual reactor connected to the winding having the largest number of turns when the rotational speed exceeds a predetermined value. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
