<p><P>PROBLEM TO BE SOLVED: To solve the problem of changing largely an output voltage from a water stream generator for generating with a water stream in association with a variation of a flow rate. <P>SOLUTION: A power generation controller for controlling the output voltage from the water stream generator includes a switching means 50 for switching a winding relating to a power generation of a winding 41 in the water stream generator from many (N) to a little (n<SB>1</SB>=N/2) or its inverse, and a controller 30 for controlling an operation of the switching means 50. When the water stream changes from a low flow rate to a large flow rate or its inverse so that the output voltage of the water stream generator reaches a set upper limit voltage or a set lower limit voltage, the switching means 50 is switched by the controller 30 based on monitoring by a voltage monitoring means to switch the number of turns of the winding 41 in the water stream generator from the many to the little or its inverse. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
