SatCon To Present Silicon Carbide Paper at EESAT, Receives New SiC SBIR Award.

BOSTON -- SatCon Technology Corporation(R) (Nasdaq NM: SATC), a developer and manufacturer of power electronics and motors for the alternative energy markets, today announced that Dr. Leo Casey from the Applied Technology division will present a paper entitled "High Power Silicon Carbide Inverter Design - 100kW Grid Connect Building Blocks" at the 2005 Electrical Energy Storage Applications and Technologies Conference (EESAT) in San Francisco on October 18th. "As our society moves towards higher levels of electrification the performance of today's power conversion technology becomes increasingly limiting," said Millard Firebaugh, SatCon President and Chief Operating Officer. "SatCon is committed to developing advanced power conversion technology that goes beyond today's Silicon based technology with Silicon Carbide being one example. Silicon Carbide should allow smaller, lighter and more robust power converter packages, which is important for all applications and is certainly true for Utility Scale Energy Storage Systems where round-trip efficiency, system reliability, volume and weight benefit directly."

The EESAT paper describes a 100kW SiC Inverter Module being developed under a DOE sponsored SBIR program. SatCon brings to the program the combination of a strong background in SiC applications R&D along with extensive experience in modular and grid connected power electronics, including utility scale energy storage experience with both batteries and flywheels. This DOE SBIR program is on-going and is focused on circuit and system design.

Meanwhile, at the more fundamental level of device packaging for Silicon Carbide, SatCon received a Phase I SBIR award from the US Army last week under a Project title of "High-Temperature Packaging Technology for Semiconductors". "The Government, through both the DOE and the DOD, recognize the significance of semiconductor technologies that allow us to go beyond Silicon," said Dr. Firebaugh, "SatCon is privileged to be in the position to use its experience and knowledge to help advance technology in this critical area".
