ADVANCED ENERGY® RECEIVES MULTIPLE POWER SYSTEMS ORDERS FROM KPE SOLAR-CELL MANUFACTURER

Global adoption of AE®’s Dressler® Cesar® RF power and Pinnacle® Plus DC systems continues as demand escalates for solar-cell products

FORT COLLINS, Colo., June 22, 2006—Advanced Energy Industries, Inc. (Nasdaq: AEIS) today announced that Hungary-based Kisgazda Polgári Egyesület (KPE)—a high-growth, solar-cell original equipment manufacturer (OEM)—has ordered multiple RF and DC power-delivery systems for integration into their plasma-enhanced, chemical vapor deposition (PECVD) and physical vapor deposition (PVD) solar-cell manufacturing equipment. The orders call for AE to provide 50 MW of solar-cell production capacity in 2006. AE has already delivered power supplies for systems with a capacity of 15 MW so far this year.

“We were looking for a power systems partner with whom we could enjoy a long-term, mutually beneficial relationship. AE is that company,” noted the KPE’s General Manager, Attila Horváth. “Because we sell complete solar-cell manufacturing equipment to companies in Thailand, China, Vietnam as well as other countries, it is critical that we work with a company possessing a strong and responsive global sales and support infrastructure. AE’s power delivery systems contribute to our success by providing the repeatability and reliability that enable us to meet the increasing global demand for solar-cell equipment.”

Dr. Hans Betz, president and CEO of AE, explained, “We are very pleased with the multi-system orders that will supply 50 MW capacity to this valued customer. As the solar-cell market segment grows, AE is well positioned with technology solutions that enable our global customers to benefit from continued industry growth. We look forward to furthering our relationship with KPE by providing advanced technology and global support to enhance their business success in the high-growth solar-cell markets.”

The AE Power Systems
Cesar RF generators are designed to meet demanding, plasma process requirements. They are available in a wide variety of frequencies (from 2 to 60 MHz) and a wide variety of power levels (from 300 W to 5 kW). Both water-cooled and air-cooled models are available. Standard features include an active front panel, large LCD display, user-friendly software, analog and serial user interfaces as well as controls for VarioMatch™ matching networks. Cesar generators are CE compliant and use field-proven Class E architecture, which enable their compact, lightweight design.

Pinnacle Plus+ pulsed DC power supplies provide higher deposition rates, more repeatable performance and exceptional film quality compared to complicated AC-power solutions for reactive sputtering and complex metallic sputtering processes. They combine standard DC technology and process-proven pulsed-DC technology patented by AE. Available in single- and dual-output 5 kW and single-output 10 kW models, they provide individually controllable dual-output pulsed DC power from a single unit; increased process flexibility (up to 350 kHz pulsing, wide full power operating voltage range); active front panel; and CE compliance.
