Title: Dexiang Zuo: Innovator in Power Supply Technology
Introduction
Dexiang Zuo is a notable inventor based in Guangdong, China. He has made significant contributions to the field of power supply technology, holding 2 patents that showcase his innovative approach to electronic circuits.
Latest Patents
One of his latest patents is the "Phase tracking pulse generation circuit and power supply device." This invention utilizes a driving pulse rising edge of a power supply as a reference. It employs a constant current circuit to charge a charging and discharging circuit at a constant current. When the reference driving pulse rising edge occurs, the charging and discharging circuit discharges. The peak voltage on the charging and discharging circuit is extracted and compared with the voltage on the circuit. When these voltages are equal, the output of a comparison circuit turns high, resulting in the phase-tracked pulse. This pulse can be used to synchronize another power supply.
Another significant patent is the "Adjustment method for LED backlight brightness." This method involves maintaining the PWM duty ratio at its maximum value if the current LED backlight brightness exceeds a preset value. It adjusts the LED backlight brightness by modifying the LED conduction current. Conversely, if the brightness is not greater than the preset value, the LED conduction current remains constant while the PWM duty ratio is adjusted. This innovative method enhances the light-emitting efficiency of LEDs, reduces backlight loss, and minimizes noise generated by the LED drive circuit.
