Original Abstract Submitted
According to one embodiment, a control device is connected to at least three or a plurality of switching controllers converting AC signals into DC signals and outputting the DC signals or converting DC signals into AC signals and outputting the AC signals. The control device is configured to generate the same number of carrier frequencies as the switching controllers, rearrange the generated carrier frequencies in ascending or descending order and calculate a difference between two adjacent carrier frequencies among the generated carrier frequencies, and if all the calculated differences between adjacent carrier frequencies are different, set one of the generated carrier frequencies as the carrier frequency of one of the switching controllers in order.
