    Abstract: 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.

    Abstract: 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.
