What Ideal Power Inc. does

In the company’s own words

Ideal Power Inc. (Nasdaq Capital Market: IPWR) operates as a semiconductor technology company focused exclusively on the development and commercialization of its proprietary Bidirectional bipolar junction TRANsistor, or B-TRAN®, solid-state switch technology. The company's website is www.idealpower.com.

Founded in Texas in 2007 and converted to a Delaware corporation in 2013, Ideal Power has transitioned from a research and development phase into early commercialization. The company has launched two commercial products: the discrete B-TRAN® and the SymCool® Power Module, both designed to address the low conduction loss requirements of solid-state circuit protection and electric vehicle contactor markets. The B-TRAN® technology represents a true bidirectional power switch that can reduce power losses by fifty percent or more compared to conventional power switches such as insulated gate bipolar transistors, or IGBTs, while reducing component count by seventy-five percent in bidirectional applications.

Ideal Power targets multiple high-growth markets including artificial intelligence data centers, solid-state circuit protection, static transfer switches, electric and plug-in hybrid electric vehicles, electric vehicle charging, renewable energy and energy storage systems, uninterruptible power supplies, industrial motor drives, solid state transformers, and power distribution applications. The company secured its first design win in late 2024 with a major Asian circuit protection equipment manufacturer for solid-state circuit breakers and entered into a multi-year strategic cooperation agreement in February 2026 for the design and development of circuit protection solutions.

The company operates with a strategic partnership model leveraging existing silicon processing infrastructure through qualified semiconductor fabrication partners. Ideal Power maintains an intellectual property portfolio comprising fifty-two issued U.S. patents and forty-seven foreign issued patents, along with seventy-six pending patent applications related to B-TRAN® technology. The company has generated three point seven million dollars in grant revenue from the U.S. Department of Energy's Advanced Research Projects Agency-Energy and has funded operations primarily through equity offerings. As of February 2026, Ideal Power employed seventeen full-time employees and had completed a public offering generating approximately twelve point six million dollars in net proceeds for further commercialization and development activities.
