Title: Yonggang Ru: Innovator in Power Supply Technology
Introduction
Yonggang Ru is a notable inventor based in Shenzhen, China. He has made significant contributions to the field of power supply technology, holding 2 patents that showcase his innovative approach to electrical engineering.
Latest Patents
One of his latest patents is a "Switching power supply with overvoltage protection and overvoltage protection method thereof." This invention includes a soft start circuit, a rectifying circuit, a filter capacitor, a main supply, an auxiliary supply, and a monitoring circuit. When the input voltage exceeds a predetermined protection voltage, a first electric control switch is turned off, shutting down the main power circuit of the switching power supply. The second electric control switch is then actuated to intermittently charge the power supply module, ensuring that the output voltage remains within a safe range. This design guarantees the safety of the devices within the power supply while allowing the auxiliary power supply and control circuit to function normally.
Another significant patent is the "Inductance-voltage clamping full-bridge soft-switch circuit." This improved circuit includes a full-bridge converter, a transformer, an output rectifying unit, an inductor, a clamping resistor, a capacitor, and two clamping diodes. The inductor features a first winding used as an auxiliary inductor and a second winding for clamping. A capacitor is connected in parallel with the clamping resistor, enhancing the circuit's efficiency and reliability.
