摘要： A fuel cell system is disclosed, which includes a fuel cell stack coupled to a load for providing power, a gas delivery system coupled to the fuel cell stack for providing fuel and oxygen to the fuel cell stack and a control system. The control system includes a forward controller for generating a desired control instruction signal based on a command from the load, and a correction controller for generating a control correction signal to avoid violating operational constraints of the fuel cell stack based on at least one measured signal from the fuel cell system. The control system generates a control signal based on the desired control instruction signal and the control correction signal, and controls the gas delivery system based on the generated control signal to ensure the fuel cell stack is operated within safe operating limits. A method for controlling the fuel cell system is also disclosed.

摘要： An exemplary motor driving system includes a power source, a driving circuit, a controller, a motor, and a protection circuit. The driving circuit including at least one switching device coupled with the power source. The motor includes a plurality of windings. The motor is coupled with the driving circuit and driven by the driving circuit. The controller is configured to provide first switch signals to the at least one switching device of the driving circuit in a normal mode. The protection circuit is coupled with the controller, and configured to generate second switch signals based at least in part on a fault signal in a fault mode and provide the second switch signals to the at least one switching device of the driving circuit so as to reconstruct circuit loops between the driving circuit and the plurality of windings. A method for operating the motor driving system is also described.

摘要： The present invention discloses a transmitting and receiving device for an ultrasonic system, which comprises a transmitter, a receiver and at least two switch circuits connected in series. The transmitter is coupled to an ultrasonic transducer and generates high voltage signals to the ultrasonic transducer during a transmitting mode. The receiver is coupled to the ultrasonic transducer via the at least two switch circuits and receives low voltage signals from the ultrasonic transducer during a receiving mode. The at least two switch circuits are configured to share voltage drop of the high voltage signals to isolate the high voltage signals during the transmitting mode and allow the low voltage signals to pass through during the receiving mode. It also discloses an ultrasonic system having the transmitting and receiving device.
