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.

Power converter control

A power converter and power conversion method wherein operation of a switching element is controlled by the frequency of a carrier wave where the frequency is varied such that the same frequency of the carrier wave is not repeated during a single modulation period.
