Ideal Power Completes Successful Proof of Concept Testing of its Double-Sided B-TRAN™

Test Results of Double-Sided Semiconductor Devices Support Third-Party Simulations

AUSTIN, Texas, March 05, 2018 (GLOBE NEWSWIRE) -- Ideal Power Inc. (NASDAQ:IPWR), an innovative power conversion technology company, has successfully completed proof of concept testing of double-sided Bi-directional bi-polar junction TRANsistor (B-TRAN™) prototypes. Tests confirmed that gain, breakdown voltage, and low conduction losses closely match characteristics from third party simulations. Two designs, a standard double-sided and a full-featured one-sided B-TRANTM, were produced by two different semiconductor fabricators. These devices validate the ability to make B-TRAN™ semiconductor power switches using conventional silicon semiconductor fabrication equipment and processes.

“This is an important step in the development of Ideal Power’s double-sided B-TRAN™ device,” said Ideal Power Chairman Lon Bell. “These results validate the fundamental properties of the B-TRAN™ structure, its potential performance, and the capability of current semiconductor manufacturing to produce the double-sided devices.”

Test results on the standard double-sided prototypes measured B-TRAN™ electrical losses at less than 40% that of conventional power switches such as silicon insulated-gate bipolar transistors (IGBTs). Ideal Power Chairman Bell added, “B-TRAN™’s enhanced switching performance translates into higher energy conversion efficiency, lower cooling complexity and fewer components in bi-directional applications compared to conventional power switches.”

The Company believes the B-TRANTM has the potential to address the multi-billion dollar power semiconductor market including solar photovoltaic inverters, microgrid power conversion systems, electric vehicle drivetrains, bi-directional energy storage, solid-state DC and AC contactors and breakers, variable frequency drives and other power conversion and control applications that could benefit from B-TRAN™’s enhanced switching performance. Ideal Power currently has 35 issued patents in the U.S. and abroad with over 40 patents pending that cover the B-TRAN™’s design, its application and manufacturing processes.

The results of this testing will be incorporated into the B-TRAN™ design and their manufacturing process. With the double-sided transistor behavior and low conduction losses confirmed, the next step is to incorporate planned corrections and improvements in the manufacturing process followed by the fabrication of prototype engineering samples for potential customers and partners.
