Latest Patents

Wanyue He's latest patents include an illumination device, an LED driver circuit, and a bleeder control circuit along with its control method. This invention provides a system where an AC input voltage is transmitted to a bus line after phase-cut processing. The bleeder control circuit features a timing module that receives a bus voltage and at least one threshold voltage to generate a first time signal. Additionally, a time processing module generates a second time signal based on the first time signal from a previous power frequency half-wave cycle. The control signal generation module then produces a first control signal for managing the bleeder circuit. The advantages of this innovation include improved operational efficiency and stability through accurate control of the bleeder circuit via bus voltage detection and adaptive control methods.

Another notable patent is the leakage protection circuit and dimming drive circuit. This invention includes a leakage detection circuit that identifies whether leakage occurs between two input terminals receiving an external signal. Upon detecting leakage, appropriate protection measures are activated. A pulse generation circuit compares a sampling signal with two thresholds to control the detection path of the leakage detection circuit. This design allows for effective leakage detection during both front-edge and rear-edge phase-cutting dimming, making it widely applicable.
