    摘要: A control system for a hybrid transmission of a vehicle, the hybrid transmission having first and second electric motors, comprises a motor speed sensor configured to measure a rotational speed of the first electric motor and a controller. The controller is configured to determine a first difference between a first measured speed and a first expected speed of the first electric motor, when the first difference exceeds a speed threshold indicative of tire slippage, temporarily adjust a torque output of the second electric motor to compensate for an oscillation generated by the first electric motor, after controlling the second electric motor to temporarily adjust its torque output, determine a second difference between a second measured speed and a second expected speed of the first electric motor, and when the second difference does not exceed the speed threshold, control the second electric motor based on a driver torque request.

    摘要: Provided is an apparatus for controlling a surge voltage. An embodiment configures a snubber coil and a snubber rectifier on a secondary side circuit in series to control a high spike surge voltage across a rectifier on the secondary side. When the rectifier is turned-off, the snubber rectifier is turned-on for a predetermined time to control the surge voltage.

    摘要: A communication device is provided. The communication device includes a circuit for reducing low-frequency interference, and the circuit for reducing low-frequency interference includes a low-frequency filter circuit and a capacitor. The low-frequency filter circuit includes a terminal and a terminal, in which the terminal is connected to a power supply, and the terminal is connected to a load; the capacitor includes a terminal and a terminal, in which the terminal is connected to the load, and the terminal is connected to the power. By setting the circuit for reducing low-frequency interference in a communication device, an input current of the communication device may be maintained stable, as a result, low-frequency interference of the communication device to other communication devices is reduced.

    摘要: This method uses 2 copies of the design under test. These 2 copies use different values (including primary inputs and initial states) to feed the supposedly irrelevant logic while using the same (or consistent as desired) values to feed the feature being verified. Symbolic method is used to efficiently determine whether the feature being verified behaves identically (or consistently as expected) in the 2 copies for all possible cases in the supposedly irrelevant logic.
