Core Viewpoint - The article highlights the successful financing and growth of "Puxi Guangjing," a company specializing in silicon carbide (SiC) special chips and system solutions, which has become one of the few profitable enterprises in the SiC sector in China [4][5]. Group 1: Company Overview - "Puxi Guangjing" was founded in March 2020 by four undergraduate classmates from Tsinghua University, focusing on the research and production of SiC special chips, modules, and power systems [4][6]. - The company has completed over six rounds of financing, amounting to several hundred million yuan, to accelerate the process of domestic substitution [6]. Group 2: Market Demand and Product Development - There is a significant increase in demand for SiC applications in extreme environments, particularly in energy exploration, where traditional silicon-based chips cannot meet the high-temperature requirements [5]. - "Puxi Guangjing" has developed SiC chips and systems that can withstand temperatures up to 230°C, addressing issues such as temperature drift and parasitic parameters in extreme conditions [5]. Group 3: Financial Performance and Production Capacity - The company has achieved profitability and has begun mass supply to major domestic energy enterprises and aerospace institutions, with a material gross margin exceeding 85% [5]. - The production base in Zhejiang supports a "virtual IDM" model, with an annual production capacity of over ten thousand special systems [5]. Group 4: Future Plans and Challenges - The company plans to optimize system costs for photovoltaic inverters, electric vehicles, and charging piles through its high-temperature technology platform, while also developing AI power supplies and high-voltage SiC modules [5]. - Technical iteration and cost pressure remain core challenges for the industry [5].
