Title: Zhiming Hu and His DC-DC Converter Innovation.

Introduction

Zhiming Hu is an inventor associated with Shenzhen, China, and Texas Instruments Corporation. His work includes a patent for a digital control approach designed to improve the stability and startup behavior of DC-DC power converters.

Latest Patents

Hu’s listed patent, “DC-DC Converter Controller Apparatus with Dual-Counter Digital Integrator,” describes a PWM controller that integrates the difference between a reference voltage and a feedback voltage. A comparator, two counters, and a digital-to-analog converter generate a compensated reference for the modulator-loop comparator, which produces the PWM switching signal used to regulate the converter’s output voltage.

The design selectively increments or decrements the second counter based on the first counter’s output after it passes through a specified count range. This mechanism is intended to enhance loop stability. The patent also describes faster integrator operation during startup and the ability to freeze integrator operation during overcurrent conditions. Hu is listed with 1 patent.
