Latest Patents
Jian-He Li holds a patent for a "Voltage waveform detector, power controller and control method for switched-mode power supplies with primary-side control." This invention discloses a voltage waveform detector, a power controller, and a control method that are adaptive for a switched-mode power supply featuring a power switch and an inductive device. The power controller includes a voltage waveform detector and a constant-current control unit. The voltage waveform detector estimates the discharge time of the inductive device when the power switch is turned off. It utilizes a differential capacitor coupled between an input node of a comparator and a feedback node, where the feedback voltage corresponds to a reflection voltage of the inductive device. The constant-current control unit integrates a current-detection signal over the discharge time to control the maximum output current of the switched-mode power supply. Jian-He Li has 1 patent to his name.
