On March 28, 2024, the financial sector reported that, according to the announcement of the China National Intellectual Property Administration, Shijiazhuang TonHe Electronic Technology Co., Ltd. had obtained a patent entitled "a high safety module DC power supply", with the authorization announcement number of CN113922476B and the application date of September 2021.



The patent abstract shows that the present invention relates to a DC power supply device, specifically to a high safety module group DC power supply. It includes multiple power supply placement enclosures, with a power distribution controller installed inside the enclosure. One side of the power supply placement enclosure is equipped with a connection plug for connecting circuits. The interior of the power distribution controller includes an APFC converter, two 220V DC choppers, and a 12V DC chopper. The present invention connects multiple batteries in parallel, making each battery a unit for use. When one of the batteries fails, it is convenient to replace the faulty battery. When replacing the battery, the entire circuit does not need to be closed, which facilitates the replacement of the battery. At the same time, a 12V DC chopper is set to adjust the voltage and store the adjusted electrical energy in the battery. When there is a feeding phenomenon in the circuit, the battery outputs voltage outward to maintain the voltage of the circuit and ensure stable operation.
