Solid-State Transformer Firm Xidi Semiconductor Raises Seed Funding

Xidi Semiconductor, a developer of advanced power semiconductor modules and a key player in the solid-state transformer (SST) sector, has successfully closed a seed funding round totaling tens of millions of RMB. The investment was co-led by prominent venture capital firms Su Chuangtou and Jingjia Investment, with Houlang Capital acting as strategic financial advisor. This capital infusion is earmarked for accelerating research and development in SST power modules, enhancing product iterations, and bolstering the company's supply chain infrastructure.

Established in 2023, Xidi Semiconductor focuses on the design, manufacturing, and sales of high-performance power semiconductor modules. Their product portfolio spans full Silicon Carbide (SiC) modules, hybrid IGBT+SiC modules, and bespoke power solutions. These technologies are finding critical applications in renewable energy storage, data center power supplies, and the rapidly evolving field of solid-state transformers. The company has already developed approximately 60 products, with over 50 entering mass production, primarily featuring SiC three-level power modules.

Xidi Semiconductor has distinguished itself in the nascent SST market, reporting the highest cumulative shipment volume in the industry, exceeding 50MW. The company's competitive edge lies in its integrated approach, offering not just power devices but also comprehensive solutions including drive design and system hardware reference architectures. This holistic offering significantly shortens development cycles for end-customers, a crucial factor in the fast-paced power electronics industry.

The company's strategic focus on SST technology addresses a critical need in modernizing electrical grids. Solid-state transformers are foundational for next-generation power systems, promising enhanced efficiency and control. Xidi Semiconductor's commitment to this area is underscored by the successful field validation of its 2MW SST power module with leading industry partners, with further customer testing underway. This advancement is particularly relevant as the global power electronics market, driven by decarbonization efforts and grid modernization, is projected for substantial growth.

Beyond SSTs, Xidi Semiconductor is also making significant strides in the energy storage sector. Responding to the market trend of increasingly large-capacity energy storage cells, the company has introduced a 430kW full SiC three-level single-module solution. This product is designed to meet the demands of next-generation large-scale energy storage systems, a market segment experiencing rapid expansion due to the proliferation of renewable energy sources.

Further enhancing its R&D capabilities, Xidi Semiconductor has developed its proprietary power electronics simulation platform, PLSIM. This internally developed tool, now in its 4.0 iteration, supports comprehensive functions from device modeling and topology simulation to thermal analysis and system-level validation. The platform's integration of AI capabilities, including intelligent agents for tasks like specification review and design verification, aims to dramatically improve development efficiency. The core team brings extensive experience from industry giants such as Delta Electronics, AOS, and Emerson, providing a strong foundation for innovation in power semiconductors and power electronics.
