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

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".
