A starting/generating system includes a rotor portion and a stator portion. The stator portion is connected to a DC power source during starting operations and to a DC load during generating operations, and includes a DC link having a first and second DC link bus, a DC link capacitor connected between the DC link buses, and an inverter/rectifier that converts AC power to DC power and vice versa. A switching device is connected in series on the first DC link bus and is controlled by a controller that turns the switching device On and Off to provide various functionality to the starting/generating system.
