Latest Patents

One of Jia-Qi Dong's latest patents is a voltage measuring apparatus for buck circuits. This apparatus is designed to be electrically connected to buck circuits and includes an equal number of RC circuits corresponding to the buck circuits. It features an analog/digital (A/D) converter, a controller, and a display unit. Each RC circuit is configured to connect in parallel with an inductor of its corresponding buck circuit. The A/D converter selectively obtains an analog voltage from one of the buck circuits and converts it into a digital voltage signal. The controller manages the A/D converter and receives the digital voltage signal, while the display unit shows a decimal voltage value based on this signal.

Another significant patent is a control circuit for switching power supplies. This control circuit comprises a power controller, a comparator, and five electronic switches. When an electronic device operates under light load, the voltage at the inverting terminal of the comparator is lower than that at the non-inverting terminal. This condition activates the first and fourth electronic switches while deactivating the second, third, and fifth switches, allowing a first power supply to be output. Conversely, under heavy load, the inverting terminal voltage exceeds the non-inverting terminal voltage, resulting in the opposite switch configuration and outputting a second power supply.
