Abstract
A power conversion device includes: a DC/DC converter including a conversion circuit; and a control circuit that detects a first voltage at an output terminal, a first current flowing through the conversion circuit, and a second voltage at an input terminal, obtains information indicating a target output voltage and a predetermined voltage, and performs calculations to emit a PWM signal for operating the conversion circuit. The control circuit performs: a first calculation for calculating a target current for approximating the first voltage to the target output voltage; a second calculation for calculating a first duty ratio for approximating the first current to the target current; a third calculation for calculating a second duty ratio based on the predetermined voltage and the second voltage; and a fourth calculation for calculating a driving duty ratio of the PWM signal using the first and the second duty ratios to control the first voltage.
