Introduction

Chao-Chih Lin is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of power conversion technology. With a total of 2 patents, his work focuses on enhancing the efficiency and functionality of power converters.

Latest Patents

One of his latest patents is titled "Controller applied to a power converter and operational method thereof." This invention involves a controller installed on the primary side of a power converter. The controller comprises a capacitor, an adjustment signal generation circuit, and a discharge circuit. The capacitor generates a tracking voltage, while the adjustment signal generation circuit produces an adjustment signal based on feedback voltage and the tracking voltage. The discharge circuit discharges the capacitor according to the feedback voltage and the adjustment signal. This tracking voltage is crucial for monitoring the state of the magnetizing current of a magnetizing inductor, facilitating zero-voltage switching (ZVS) control and quasi-resonant (QR) control of the power converter.

Another significant patent is "Dummy load controllers and control methods for power supplies capable of quickly lowering output voltage at output node." This invention provides a dummy load to reduce output voltage under light-load or no-load conditions. The power converter features a primary winding and a secondary winding that are isolated from each other. The secondary winding can de-energize to supply output voltage for powering a load. The winding voltage across the secondary winding is monitored to determine a non-switching time, which is compared against a predetermined reference time. If the output voltage exceeds a set threshold, a discharge current is utilized as a dummy load to lower the output voltage.
