Abstract
In a power converter including an inverter configured to convert a direct current voltage into an alternating current voltage by controlling switching devices to be turned ON or OFF based on a control signal and to output the alternating current voltage to a load, a carrier wave frequency is changed. A command value is compensated in accordance with the changing carrier wave frequency. The control signal results from a comparison of the carrier wave with a compensated command value. As a result of the compensation, output fluctuations caused by an error voltage between the command value and an output voltage to the load can be suppressed.
