Title: Che-Hao Kuo: Innovator in LED Technology
Introduction
Che-Hao Kuo is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of LED technology, holding 2 patents that focus on improving the performance and efficiency of LED lighting systems.
Latest Patents
One of his latest patents is a secondary-side bucking and current-stabilizing flyback power converter. This innovative device adopts a dual-stage isolated circuit architecture, which outputs a constant current to drive low-power LED modules. The primary stage utilizes a flyback circuit architecture with a regulated voltage, while the secondary stage employs a buck circuit architecture for current stabilization. This design effectively senses the load effect of the output current at the LED module, regulating the output cycle to maintain a constant total output current and reduce ripple amplitude. As a result, it achieves a non-strobe output, significantly improving the illumination effect of the LED module.
Another notable patent is a driver circuit designed to improve LED flickers. This circuit features a primary side regulating architecture and an isolation transformer. It includes several components such as a transformer, a primary side regulating module, a feedback portion, a driving module, and a dimming portion. The transformer consists of an input coil, an auxiliary coil, a driving coil, and a dimming coil. When a dimming signal with a voltage of 1V-10V is inputted to the dimming portion, the driver circuit effectively reduces flicker when applied to panel lights.
