Latest Patents

Wangrui Guo's latest patents include a "Boost converter with short-circuit protection and method thereof." This patent discloses a method for protecting a boost converter from short-circuit events. The method involves turning on a switch in the switching circuit and supplying a control voltage that gradually increases. The current flowing through the switch is monitored and compared to a predetermined value. If the current exceeds this value, the switch is turned off, and a preset time period is initiated to check for short-circuit events at the output terminal. If a short-circuit is detected, the protection switch is turned off to prevent damage.

Another significant patent is the "Reference compensation module and switching regulator circuit comprising the same." This invention relates to a switching regulator circuit that compensates for reference signals. The circuit features a reference ground with an average offset voltage proportional to the output current. The reference compensation module is designed to receive a second reference signal and provide a first reference signal that cancels out the average offset voltage, ensuring accurate performance of the switching regulator.
