An apparatus to deliver an alternating current (AC) power may include a controller having a processor and a memory. The apparatus may also include a plurality of power inverters in communication with the controller. Each power inverter may be configured to convert direct-current (DC) power into the (AC) power. Each of the plurality of power inverters may be configured to be controlled by the controller to generate AC power below at least one predetermined operating threshold. The plurality of power inverters may be configured to combine AC power generated by each of the plurality of power inverters, such that the combined AC power is delivered to a common AC load above the predetermined operating threshold. The apparatus may be arranged and operated according to a ratio of FMA=Fr/N, where Fr=fs/fl, fs is the switching frequency of the plurality of power inverters, fl is the frequency of the common AC load, and N is the number of power inverters of the apparatus. |
