Title: Qiu Sha: Innovator in Power Conversion Technology
Introduction
Qiu Sha is a prominent inventor based in Cupertino, CA, known for his significant contributions to power conversion technology. With a total of 10 patents to his name, Qiu has made remarkable advancements in the field of switching power supplies and flyback converter controllers.
Latest Patents
One of Qiu's latest patents is the "Adaptive startup for switching power converter." This invention provides a switching power supply controller that measures input voltage through an application of a load during an input voltage measurement period. This measurement occurs after the switching power supply is connected to an AC mains. Based on the measured input voltage, the controller adjusts the start-up delay period, ensuring it remains substantially constant despite variations in the AC line voltage.
Another notable patent is the "Flyback converter controller with single pin detection of over-voltage and auxiliary winding faults." This invention features a flyback converter controller that utilizes a single terminal to sense over-voltage faults for an input voltage and detect open circuit faults for an auxiliary winding. A first voltage divider provides a divided version of the input voltage to the single terminal, allowing the controller to compare the voltage to at least one over-voltage threshold for fault detection.
