Delta Electronics (ISIN TW0002308004) unveiled a solid-state transformer-based microgrid system for AI factories and data centers on October 14, 2026. The system offers efficiency of up to 98.5 percent, according to Delta. The announcement came as the company faced a US patent investigation involving vertical power delivery systems.

Microgrid targets AI power demand

Delta presented the system at Energy Taiwan 2026 for AI factories, high-density computing and smart manufacturing. The modular design combines a solid-state transformer, direct-current converters and control equipment, while Delta said trial production is planned by the end of 2026.

The company also highlighted an efficiency range of up to 4 to 5 percent improvement from grid to chip in AI data centers. That places power conversion and thermal management at the center of Delta's growth case as server loads rise.

What does the probe mean for margins?

Chronology shows three dated developments. On October 7, 2026, Delta reported September sales of TWD 65.4 billion. On October 11, 2026, the USITC investigation named Delta among 20 respondents, as Focus Taiwan reported. On October 14, 2026, Delta unveiled the microgrid system with up to 98.5 percent efficiency.

The sales figure provides a counterweight to the legal headline. TokenPost reported that September revenue increased 14.6 percent year over year to TWD 65.4 billion, while revenue for the first nine months reached TWD 539.668 billion, up 37.2 percent. The same report said Delta's production and supply schedules had not been materially affected.

Next date for investors

Delta's investor-relations page lists October 29, 2026, for its third-quarter analyst meeting, providing the next scheduled company event and a near-term date for management commentary.
