Latest Patents

One of Yu-Jen Lin's latest patents is the "Totem-pole power factor corrector with zero-voltage switching." This invention involves a totem-pole power factor corrector that receives an input power source and converts it into an output power source. The design includes an input inductor, a fast-switching switch leg, a slow-switching switch leg, a resonant tank, and an output capacitor. The fast-switching switch leg features a fast-switching upper and lower switch, which are coupled at a first middle node. The slow-switching switch leg operates in parallel and includes its own upper and lower switches. The resonant tank is composed of a resonant inductor and at least one resonant capacitor, facilitating efficient power conversion.

Another significant patent is the "Dual mode charge control method." This method involves detecting various parameters such as input voltage, resonance current, output current, and output voltage. It employs a single-band charge control during light-load or no-load conditions, compensating the output voltage to generate an upper threshold voltage. The method utilizes a resettable integrator to calculate resonance voltage and generates control signals to manage the power switches in the resonance circuit.
