Latest Patents

Yu Xu's latest patents include a "Large-current power supply and constant-current control method and system thereof." This invention discloses a system and method for large-current power supply and constant-current control. The large-current power supply consists of a primary power supply, an energy-feedback circuit, and a direct-current (DC) large-current generator. The energy-feedback circuit includes a freewheel diode and a magnetic reset winding, while the secondary coil of the DC large-current generator is connected to the load. This design eliminates the need for an output rectifier diode and filter capacitor, addressing power consumption issues and significantly prolonging the service life of the power supply. The system is characterized by a simple circuit, small size, easy control, and high working reliability.

Another notable patent is the "Quick start control method and system for buck circuit." This invention provides a method for controlling the duty ratio of a switch in a Buck circuit during the initial start time period. By managing the duty ratio effectively, the output voltage can rise rapidly, and the capacitor can be charged efficiently. This method reduces overshoot and oscillation during the start process, thereby shortening the start time of the Buck circuit.
