    摘要： The present disclosure is directed to an electric drive. The electric drive may include a first power inverter, a second power inverter, and a positive DC bus connecting the first power inverter and the second power inverter. The electric drive may also include a first switch connected to the positive DC bus between the first power inverter and the second power inverter. The electric drive may include a second switch connected to the positive DC bus between the first power inverter and the second power inverter. The electric drive may further include a control unit connected to the first switch and to the second switch. The control unit may be configured to selectively allow current to pass through the first switch and the second switch.

    摘要： An electric machine and method for powering the electric machine using interchangeable power modules that are configured to be interchangeably placed within power bays of the electric machine is disclosed. The electric machine includes an electrical module that is configured to receive power from one or more of the power modules placed in the power bays and transform, such as from DC to multi-phase alternating current (AC), and provide the power to one or more motors of the electric machine. The power modules may be of the same dimensions, same electrical interfaces, and/or same power output (e.g., type, magnitude) as each other to enable the interchangeability of the power modules. The power modules may be ones that generate power or ones that store energy. In some cases, the generating power modules may charge the energy storage power modules, while the energy storage power modules power the electric machine.
