Title: Lin Cheng and a Multi-Converter Off-Grid Startup Invention

Introduction

Lin Cheng is an inventor associated with Nanjing, China, and Sungrowpower Supply (Jiangsu) Co., Ltd. His patent work addresses the operation of multiple converters when a power grid is unavailable or fails.

Latest Patents

The provided information lists 1 patent for Lin Cheng: “Multi-converter parallel connection system and off-grid startup method.” The invention describes a voltage regulation method for a system of at least two converters whose alternating-current sides connect to a shared bus. When the system is disconnected from the grid or the grid fails, a group of converters switches from current-source mode to voltage-source mode to establish the bus voltage. The remaining converters then switch to voltage-source mode after that voltage has been formed.

Career Highlights

Cheng’s listed patent focuses on coordinating converters during off-grid startup. By sequencing the mode changes, the method provides a way to establish an alternating-current bus voltage and bring the other converters into voltage-source operation.

Collaborations

The provided information identifies Ye Xu and Haitao Li as Cheng’s coworkers. Their specific roles in the patent or related work are not stated.

Conclusion

Lin Cheng’s listed invention concerns a coordinated approach to establishing bus voltage when a multi-converter system operates without a functioning grid.
