<p>Provided is a power supply device that supplies the power output from a power generator to a power load, can be easily attached to an existing power generator system, and also, although having a simple configuration, can suppress the variation of the power output from the power generator even if the power load fluctuates. The power supply device that supplies the power output from a power generator to a power load comprises: a power detector for detecting the load power of a power load; a low-pass filter for detecting the first-order lag value of the load power; a differential device for obtaining the difference value between the load power detected by the power detector and the first-order lag value detected by the low-pass filter; a power converter operating using, as a command value, the difference value obtained by the differential device; and an electricity storing means for transferring power to and from the power generator and the power load via the power converter.</p> |
