Abstract:
Embodiments herein relate to a three-phase paralleled passive front-end drive, that includes a rectifier bridge, a coupling reactance operably connected to the rectifier bridge and configured to transfer power from the rectifier to a first direct current (DC) bus, and a bus coupler operably coupling the first DC bus to a second DC bus. The paralleled drive also includes a first inverter operably connected to the first DC bus; a second inverter operably connected the second DC bus, the first inverter and second the inverter each configured to provide a plurality of motor excitation signals, respectively. The paralleled drive also includes a plurality of interphase inductors operable to combine the plurality of motor excitation signals from the first inverter with the plurality of motor excitation signals from the second inverter.
