A variable speed drive (104) is provided having a converter (202) to convert an AC voltage to a DC voltage, a DC link (204) to filter and store energy from the converter (202), and a plurality of inverters (206), wherein each inverter (206) is configured to convert a DC voltage to an AC voltage to power a corresponding load connected to the inverter (206). The converter (202) is electrically connected to an AC power source, the DC link (204) is electrically connected to the converter (202), and the plurality of inverters (206) are electrically connected in parallel to the DC link (204). Each inverter (206) of the plurality of inverters (206) is configured to operate substantially independently of other inverters (206) of the plurality of inverters (206).
