Title: Jinhu Cao and Multi-Converter Parallel Connection Technology.

Introduction

Jinhu Cao is an inventor based in Nanjing, China, associated with Sungrowpower Supply (Jiangsu) Co., Ltd. His patent work includes a method for starting and regulating a multi-converter parallel connection system when it is disconnected from the power grid or the grid fails.

Latest Patents

Cao is named on 1 patent: “Multi-converter parallel connection system and off-grid startup method.” The invention concerns a system with at least two converters whose alternating-current sides connect to a shared AC bus. When the system is off-grid or the power 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. This staged startup method addresses voltage formation in a parallel converter system.

Career Highlights

Cao’s listed patent reflects work on power-conversion systems and off-grid startup methods. His association with Sungrowpower Supply (Jiangsu) Co., Ltd. connects his inventive activity with the company’s work in power technology.
