Latest Patents

One of Yung-Chih Lai's latest patents is the "Flyback power converter circuit and high voltage start-up circuit thereof." This invention features a flyback power converter that includes a transformer with an auxiliary winding for generating an auxiliary voltage. It provides a supply voltage on a supply node, powered by a primary side controller circuit. The high voltage start-up circuit is coupled to a high voltage signal and generates the supply voltage through a supply output terminal. This design ensures that when the supply voltage does not exceed a start-up voltage threshold, a high voltage start-up switch conducts to provide the necessary supply voltage. When the supply voltage exceeds the threshold, the switch turns off, enhancing the circuit's reliability.

Another notable patent is the "Signal peak detector and detection method, and control IC and method for a PFC converter." This control integrated circuit for a power factor correction converter includes a pin for detecting both alternating-current and direct-current information of an input signal. The signal peak detector within the circuit identifies the peak value of the input signal, allowing for a reduction in pin count while maintaining functionality.
