Title:
電源装置
Document Type and Number:
Japanese Patent JP4791689
Kind Code:
B2
Abstract:
A power supply apparatus comprises a power generating device in which the output power supplied to a load varies depending on a power generating condition; a current detection part for detecting the current output from the power generating device; a target output voltage setting part for setting a target output voltage of the power generating device; an error amplifier for amplifying the error between the voltage output from the power generating device and the target output voltage and outputting an error signal; a current control part for receiving input of the error signal, controlling the output current of the generating device so as to make the absolute value of the error signal small and outputting it to external output terminals; and an operation part for calculating the target output voltage as a desired operating condition of the power generating device by a predetermined function having at least the current detected by the current detecting part as an input parameter, and issuing it to the target output voltage setting part.
