Abstract
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.
Claims7
A starting/generating system comprising:
- a rotor portion;
- a stator portion located to interact with the rotor portion, and for connecting to a DC power source during starting operations and to a DC load during generating operations, the stator portion comprising:
- a DC link having a first DC link bus and a second DC link bus;
- a DC link capacitor connected between the first DC link bus and the second DC link bus;
- an inverter/rectifier connected to convert DC power to AC power during starting operations and to convert AC power to DC power during generating operations;
- a switching device connected in series on the first DC link bus;
- and
- a controller connected to control the state of the switching device, wherein the controller selectively controls the state of the switching device to provide various functionality depending on the operating state of the starting/generating system.
