Title: Haibin Cao and Discontinuous Pulse-Width Modulation

Introduction

Haibin Cao is an inventor based in Shenzhen, China, whose patent work addresses power modulation and the management of electrical stress in common-mode suppressor units. The supplied information identifies him as a man and lists Shenzhen Vmax New Energy (Group) Co., Ltd. as his company.

Latest Patents

Cao is associated with 1 patent, titled “Discontinuous Pulse-Width Modulation Method.” The invention shifts a three-phase modulation wave upward and downward, then uses the resulting modulation waves and zero-sequence components to determine the start and end points of a transition interval and a target zero-sequence component. Adding that target component to the original three-phase modulation wave produces the target modulation wave.

According to the patent description, the method slows changes in the modulation wave during the transition interval. This can reduce voltage and current oscillations in the common-mode suppressor unit and lower stress on its components.

Career Highlights

Cao’s listed patent reflects work on modulation techniques intended to improve the operation and durability of power-electronics equipment. His professional affiliation is Shenzhen Vmax New Energy (Group) Co., Ltd.

Collaborations

The supplied information names Jun Liu and Jinzhu Xu as Cao’s coworkers. It does not specify their roles in the patent or describe particular collaborations.

Conclusion

Haibin Cao’s patent focuses on shaping a transition in three-phase pulse-width modulation to help mitigate oscillations and reduce stress on common-mode suppression equipment.
