1results about How to "Avoid abnormal operation" patented technology

This application provides a high-voltage DC power supply assembly, relating to the field of electronic technology, comprising: a reverse connection and backflow prevention module for connecting the power supply circuit when on and blocking backflow current from the energy storage module to the input terminal of the power supply assembly when off, and being in a off state when the input terminal of the power supply assembly is reverse connected; an energy storage module for providing energy to downstream loads when the power supply assembly is powered off; a reverse current detection module for real-time monitoring of whether there is reverse current flowing from the energy storage module to the positive bus, and generating a detection signal characterizing the reverse current state; and a control module for outputting a control signal to turn off the reverse connection and backflow prevention modules within a preset time when current backflow is detected based on the detection signal. Implementing the technical solution of this application achieves the effect of improving system reliability.
