Abstract
To provide a power converter which can maintain the stability and the response of the feedback control system, even if the frequency characteristic of the chopper circuit changes according to change of driving condition. A power converter is provided with a chopper circuit which has reactor and switching device; and a control circuit which changes a feedback value of duty ratio of the switching device so that a deviation between a target value of output voltage and a detection value of output voltage approaches to 0, wherein the control circuit changes a frequency characteristic of the feedback control, based on at least any two or more of information on the output voltage, information on an input voltage, and information on duty ratio.
