Title: Innovations by JooHoon Kim
Introduction
JooHoon Kim is a notable inventor based in Bucheon, South Korea. He has made significant contributions to the field of semiconductor technology, holding three patents to his name. His work primarily focuses on power switch control and feedback mechanisms in power converters.
Latest Patents
JooHoon Kim's latest patents include a "Switch controller and compensation method of valley detection error." This method operates a switch controller of a power switch by determining a compensation value based on a quarter period of a resonant cycle of a drain voltage and a propagation delay time. The drain voltage is the voltage at the drain of the power switch. The method generates a sensing signal based on the detection of a valley point of the drain voltage and produces a control signal for managing the power switch. This control signal is based on the sensing signal and the compensation value, allowing the power switch to be turned on at the appropriate time corresponding to the valley point of the drain voltage.
Another significant patent is the "Circuit and method for controlling power converter based on feedback current." This controller includes a feedback sensing circuit that generates a feedback current during a specific time interval in a switching period of a power converter. The feedback current is based on the output voltage of the power converter and generates a digital sensing signal indicative of the duration of the first time interval. The feedback signal generator determines the magnitude of the feedback current flowing during this interval and generates a digital feedback signal based on this magnitude. The controller adjusts the output voltage of the power converter in response to the digital feedback signal.
