Title: Innovations of Guanghua Ye
Introduction
Guanghua Ye is a notable inventor based in Dongguan, China. He has made significant contributions to the field of electronics, particularly in power systems. With a total of two patents to his name, his work focuses on enhancing the efficiency and functionality of power conversion systems.
Latest Patents
One of Guanghua Ye's latest patents is the "Synchronous clock generator circuit for multiphase DC-DC converter." This invention introduces a synchronous clock generator designed for multiphase DC-DC converter systems. It includes a front-end buffer circuit, a ramp signal generator circuit, a configurable equally divided reference voltage generator circuit, a set of comparators, a 10-ns pulse generator, multiple 30-ns pulse generators, and a pulse combination circuit. The synchronous clock generator can produce a clock pulse signal SYNC at N times the single-phase switching frequency. Within one synchronous loop period, a 10-ns pulse is generated, followed by N-1 30-ns pulses. The master power stage chip detects the 10-ns pulse, while all slave power stages detect and count the 30-ns pulses to determine when to set their output signal PWM. This invention allows for the immediate production of the new SYNC signal with balanced phase shift, accommodating changes in the total phase number N through a total phase number register.
Another significant patent is the "Multi-section current sense method for monolithic power system." This invention comprises multiple power sections and a multi-input operational amplifier. The pilot device is placed at different locations of the main power MOSFET to form multiple individual power sections. The multi-input operational amplifier drives a transistor to detect the overall current of each power section and report the overall current to the system.
