    FORT COLLINS, Colo., April 18 /PRNewswire-FirstCall/ -- Advanced Energy
 Industries, Inc. (Nasdaq:   AEIS) today announced that its Dressler(R)
 Cesar(R) RF generators and VarioMatch(TM) matching networks have been
 chosen by Energy Conversion Devices, Inc. to provide process power for the
 25 MW photovoltaic (PV) manufacturing equipment being manufactured by ECD
 Ovonics for United Solar Ovonic, its wholly owned subsidiary. Together, the
 Cesar RF generator and VarioMatch matching network comprise a full-featured
 RF power delivery system that meets ECD Ovonics' critical specifications.
 United Solar Ovonic's unique UNI-SOLAR(R) PV products are flexible,
 substantially lighter and more rugged than other solar cell products and
 actually become an attractive part of the building's roof, replacing
 roof-top arrays.
