Abstract
A machine is described that includes an electric drive for propelling the machine along a ground surface. The machine includes an electric power supply system configured to deliver operating electrical power to the electric drive. The electric power system includes a first generator and a second generator. The electric power system also includes a first rectifier coupled to the first generator and having a first direct current (DC) output and a second rectifier coupled to the second generator and having a second DC output. Both the first DC output and the second DC output are coupled to the single DC bus, thereby providing an arrangement for the first rectifier and the second rectifier to simultaneously provide power to the single DC bus. The electrical power system also includes a first inverter/controller coupled to the single DC bus and configured to provide a controlled alternating current to a first motor.
