A recently granted patent (Publication Number: US11930573B2) discloses a power supply device featuring a power converter, a blocking switch, and a controller. The controller is equipped with detection circuits to monitor output power variations and electrical characteristics of the power converter and blocking switch. Based on the relationship between these detection results, the controller determines whether to limit the output power to comply with specific requirements, ensuring efficient power management.

Furthermore, the power supply device includes additional components such as a detection resistor, an optocoupler, and a synchronous rectifying switch, each contributing to the monitoring and control of the output power. By detecting parameters like voltage differences, current values, and switch operation times, the controller can make informed decisions on regulating the power output. Additionally, the device is designed to supply power through a communication cable following a Type-C protocol, with the controller monitoring voltage differences between channels to further optimize power delivery. Overall, the patented power supply device offers a sophisticated system for efficient power management and compliance with specific power source requirements, enhancing its utility in various applications.
