Latest Patents
One of his latest patents is the "Self-excited TRIAC dimming circuit." This innovative circuit is designed for panel lights and includes a dimming module along with a conversion module. A power factor controller (PFC) is integrated into the dimming module, while the conversion module features a self-excited electronic isolation transformer. This design improves overall circuit stability, ensuring that the panel light meets high safety standards, thereby enhancing its applicability and competitiveness in the market.
Another notable patent is the "LED driver circuit for supplying TRIAC holding current by using controllable current source." This circuit employs a single-stage power factor correction architecture. It receives input voltage from a conversion module to generate an operating current that drives an LED light source. The circuit monitors input voltage changes through a control chip and utilizes a fixed cut-off time switching method. This ensures that the controllable current source outputs a constant operating current, which is always greater than the holding current required by the TRIAC element.
