Abstract: A power converter includes a converter, an inverter, and a control unit. The converter converts electric power supplied from a power supply side to DC power. The inverter is provided on an output side of the converter. The control unit is configured to calculate a control difference between a target value for a target control voltage in a DC section provided on the output side of the converter and a feedback value using a DC voltage of the DC section as the feedback value, to perform a nonlinear operation process on the control difference, and to calculate an operation value based on a result of the nonlinear operation process and control the converter using the operation value.
