Latest Patents

Kai Deng holds a patent for a "Fault detection method and fault protection method for power conversion system, and power conversion system." This invention relates to the technical field of fault detection for circuits. The fault detection method involves controlling an alternating current pre-charge power supply to charge a bus capacitor of the power conversion system. This bus capacitor supplies power to a digital signal processor (DSP) through a first switch power supply (SPS). The method determines whether the DSP is energized to obtain a first determination result. If the first determination result indicates that the DSP is de-energized, it is determined that the bus capacitor is short-circuited. This innovative approach allows for the detection of short-circuit faults in the bus capacitor of the power conversion system.
