BPS has been granted an invention patent authorization: "Switching Power Supply Controller, Switching Power Supply System, and Switching Power Supply System Power Supply Method"

Article Source：Qichacha | Author：Securities Star News | Issuing Time：2024.04.11
Securities Star News: According to data from Qichacha, BPS (688368) has obtained a new invention patent authorization, titled "Switching Power Supply Controller, Switching Power Supply System, and Switching Power Supply System Power Supply Method". The patent application number is CN202010506989.9, and the authorization date is February 27, 2024.



Patent Abstract

The present invention provides a switch power supply controller, a switch power supply system, and a power supply method for a switch power supply system. The switch power supply controller comprises an output voltage power supply unit located within the same package, a built-in energy storage unit, and a logic control unit. The output voltage power supply unit is used to charge the built-in energy storage unit using the output voltage of the switch power supply system, and the built-in energy storage unit is used to provide working voltage to the logic control unit. This not only eliminates the need for external energy storage capacitors, but also utilizes output voltage for power supply, significantly reducing power loss and achieving lower standby power consumption. Furthermore, the switch mode power supply controller further includes a high-voltage power supply unit to achieve a hybrid power supply method of combining output voltage power supply and high-voltage power supply. In switch mode power supply systems that require high-voltage power supply, the opportunity for output voltage power supply is fully utilized, and the proportion of direct power supply from high-voltage power supply units is minimized to achieve lower standby power consumption.

Since the beginning of this year, BPS has obtained 9 new patent authorizations, an increase of 350% compared to the same period last year. Based on the company's mid year financial data for 2023, the company invested 189 million yuan in research and development in the first half of 2023, a year-on-year increase of 2.05%.
