Abstract: A motor inverter is provided. The motor inverter is coupled to an input power source and a motor and controls the mechanical switch to receive or turn off the input power source. The motor inverter includes primary and secondary auxiliary circuits, a microprocessor, a gate driver, and a motor drive circuit. The primary and secondary auxiliary circuits are coupled to the input power source and outputs first and second output voltages respectively. The microprocessor operates the driving switches of the motor drive circuit through the gate driver to switch the input power source for driving the motor. If the microprocessor determines that the first output voltage is abnormal and the motor rotational speed exceeds a safe speed limit, the microprocessor controls the driving switches to form an active short circuit for stopping the motor, and the microprocessor turns off the mechanical switch for protecting the input power source.

Abstract: A memory device is provided, including a memory array, a driver circuit, and recover circuit. The memory array includes multiple memory cells. Each memory cell is coupled to a control line, a data line, and a source line and, during a normal operation, is configured to receive first and second voltage signals. The driver circuit is configured to output at least one of the first voltage signal or the second voltage signal to the memory cells. The recover circuit is configured to output, during a recover operation, a third voltage signal, through the driver circuit to at least one of the memory cells. The third voltage signal is configured to have a first voltage level that is higher than a highest level of the first voltage signal or the second voltage signal, or lower than a lowest level of the first voltage signal or the second voltage signal.
