Title:
電圧変換装置
Document Type and Number:
Japanese Patent JP5206489
Kind Code:
B2
Abstract:

To provide a voltage conversion device having improved controllability of the output voltage.

A control device includes a PID controller 523, which calculates a feedback voltage command in the feedback control based on a control gain and an error between the detected output voltage and the command voltage; and a gain determining part 522 which determines control gains PG, IG, DG used by a feedback control part based on the output voltage VH or the demand voltage Vdccom so that the voltage trackability of the output voltage VH to power consumption, at a load connected to an output of a voltage converter 12 approaches uniformity, even if the output voltage VH applied to a capacitor C2 is changed.
