Zusammenfassung:	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.
