BEIJING – April 2, 2026 – Under the theme “Smart, Reliable Power for AI,” SIFANG Digital Energy today unveiled its SST 1.0 product, a solid-state transformer designed to meet the growing power demands of artificial intelligence data centers (AIDCs). The launch event brought together industry experts, corporate representatives, and media to Beijing.
The event opened with remarks from Mr. Liu Zhichao, President of SIFANG, who welcomed attendees and highlighted the rapid growth of AI and AIDCs. “Computing power has become the core productive force of the digital economy, bringing new challenges to power supply architectures,” he said. Mr. Liu noted that SIFANG’s deep experience in DC distribution and microgrids has laid a strong technical foundation for AIDC power solutions, and that the SST 1.0 marks a major step forward in addressing these challenges.
Ms. Jiang Ying, China Market Director for Distribution Solutions at ABB Electrification China and head of digital solutions, delivered a keynote on AIDC development trends and future architectures. Drawing on industry data and her experience, she traced the evolution of AIDC data centers, analyzed power distribution system architectures, and discussed the synergy between computing and power within AIDCs. She also offered a broad outlook on deeper integration across the AIDC industry.
Mr. Mei Hongming, CTO of SIFANG Digital Energy, reviewed the company’s nearly 20-year history in power electronics, including innovations in power quality, unit control, special power supplies, energy storage and grid-forming, and flexible AC/DC transmission. He explained that SIFANG’s accumulated expertise in DC distribution has positioned the company to deliver critical equipment for AIDC power scenarios, including solid-state transformers, supercapacitor energy storage, medium-voltage cascaded energy storage, and multi-port SSTs.
The highlight of the event was the official launch of the SST 1.0. Mr. Wang Jikang, CMO of SIFANG Digital Energy, described the product as a next-generation power solution for data centers. “It enables medium-voltage AC to directly power an 800V DC energy platform, making DC load power supply simpler, more efficient, more controllable, and grid-friendly,” he said.
