Leyi Tong Technology has obtained patents related to inverter power supply circuits, combined with energy storage to reduce battery load and ensure stable RTC operation.

On March 28, news was released that the National Intellectual Property Administration indicated that Huizhou Leyitong Technology Co., Ltd. applied for a patent named “Real-time RTC Clock Power Supply Circuit for Hybrid Inverter,” with the authorization announcement number CN224053909U, and the authorization announcement date being March 27, 2026. The application number is CN202520703357.X, the application publication date is March 27, 2026, the application date is April 15, 2025, and the inventors are Wei Jiansheng, Li Jinzhou, and Xie Xiaokun. The patent agency is Beijing Zhongda Dequan Intellectual Property Agency Co., Ltd., and the patent agent is Liu Jie, with classification numbers H02J7/34, H02J9/00, H02J7/00, and H02J7/90.

The patent abstract shows that this application proposes a real-time RTC clock power supply circuit for a hybrid inverter, which includes: an inverter, supercapacitor, battery, MOSFET Q1, MOSFET Q2, and RTC clock; when the main power supply is normal, it is powered by the inverter; when the main power supply is interrupted, MOSFET Q2 is turned on, and MOSFET Q1 is turned off to discharge the supercapacitor; when the supercapacitor discharges to a set threshold, MOSFET Q2 is turned off, and MOSFET Q1 is turned on, switching to battery power supply. This application combines the composite energy storage of batteries and supercapacitors, where the supercapacitor provides a large instantaneous current in the short term, reducing the burden on the battery, thus slowing down the battery consumption rate and significantly extending the overall lifespan of the system, while also possessing strong environmental adaptability. It effectively improves the stability and reliability of the system in various harsh environments, avoiding downtime or data loss issues due to battery failure or depletion, ensuring that the RTC can continue to operate stably.

According to Tianyancha data, Huizhou Leyitong Technology Co., Ltd. was established on November 2, 2016, with the legal representative Zhou Quanfu, belonging to the manufacturing industry of computers, communications, and other electronic devices.
