Zhuhai Jiuyuan Power Electronics Technology Co., Ltd.
Founded in 2013 and headquartered in the High-Tech Zone of Zhuhai, Guangdong, Zhuhai Jiuyuan Power Electronics Technology Co., Ltd. is a national high-tech enterprise and a Guangdong Provincial Specialized, Sophisticated, and Innovative ("Little Giant") Enterprise with core proprietary technologies and full intellectual property rights. The company has long been dedicated to the R&D, production, and sales of high-end new energy power conversion equipment and intelligent testing products, establishing itself as an industry leader in this field in China.
Core Competitiveness
Jiuyuan’s competitive edge stems from its strong R&D capabilities and breakthrough technologies. The company focuses on the R&D and industrialization of key technologies such as lithium battery performance testing, energy storage converters (PCS), and grid simulation systems. Its self-developed "shared DC bus inside equipment" core technology has successfully solved the long-standing industry challenge of high energy consumption in new energy testing, significantly reducing system power usage while achieving an industry-leading 98.5% energy feedback utilization rate in testing systems. This core technology not only enhances the company’s key products but also exhibits strong extensibility, enabling applications in broader fields such as clean energy power generation equipment, rail transit power supplies, and microgrid integrated energy conversion systems.
