Latest Patents

One of Ji-Chao Li's latest patents is a power supply test device. This device includes a function generator, a loading circuit, a current detection circuit, and a controller. The function generator outputs a square-wave signal to the loading circuit, which is electronically connected to a power supply. The loading circuit regulates the output current of the power supply according to the square-wave signal. The current detection circuit works with the controller to detect the slope of the output current. The controller compares the detected slope with a preset value and adjusts the square-wave signal accordingly to regulate the slope of the output current.

Another notable patent is a system for supplying operating voltage to a central processing unit (CPU). This CPU power controller consists of a power supply unit, a CPU power controller, a detecting circuit, a temperature compensation circuit, an inductor, a thermistor, first and second switches, and first and second capacitors. The detecting circuit outputs a detected voltage of the inductor to the CPU power controller. The temperature compensation circuit outputs a detected voltage of the thermistor to the CPU power controller to compensate for changes in the voltage of the inductor. If the detected voltage exceeds the rated voltage, the first switch opens while the second switch closes, allowing the inductor to discharge. Conversely, if the detected voltage is below the rated voltage, the first switch closes and the second switch opens, enabling the power supply unit to charge the inductor and increase the CPU voltage.
