A paralleled drive having a first plurality of interphase inductors to distribute three phase alternating current power to a first and a second converter that transfer power to a first and a second direct current (DC) buses respectively, a bus coupler connecting the first and second DC buses, a first and a second inverter connected to the first and second DC buses respectively. The drive also includes a controller connected to the first and second converters and the first and second inverters, the controller generates control signals to cause the first and second converter to transfer power to the first and second direct current (DC) buses respectively, and the controller configured to generate control signals to cause the first and the second inverters to generate a plurality of motor excitation signals respectively, and a second plurality of interphase inductors operable to combine the plurality of motor excitation signals.
