AEG Power Solutions Thyrobox M sets new industry benchmark for polysilicon power supplies

UK: AEG Power Solutions has launched the Thyrobox M, its newest generation of products, at the Photon Photovoltaic Technology Show in Stuttgart, Germany in April 2010.

With advanced process monitoring capabilities, a 0.95 power factor and more than 99 percent energy efficiency, the Thyrobox M delivers unprecedented performance, reliability and stability to polysilicon manufacturers worldwide.

“Our customers have told us that they want to increase production and enhance purity while reducing their operating costs, especially for energy consumption per kilogram of polysilicon,” said Gladwyn De Vidts, AEG Power Solutions’ Vice President Power Control Solutions Division. “Our Thyrobox M solution improves process stability, reduces down time and provides exceptional energy efficiency. It responds to customer needs and reinforces AEG Power Solutions’ position as the technology leader in
polysilicon power.”

AEG Power Solutions commissioned the first Thyrobox, the power supply family specially developed for the polycrystalline silicon deposition process, over 25 years ago.

Engineered with a modular design, the Thyrobox M is the world’s most compact polysilicon power supply. Depending on the type of reactor, its footprint is about 25 percent smaller than older Thyrobox solutions and up to 70 percent smaller than competing products. The compact design reduces installation, commissioning and maintenance costs for the entire energy supply as well as building costs.

Additional Thyrobox M features include, warning system and troubleshooting minimize the risk of process interruptions in case of silicon rod cracks or melts, integrated medium-voltage ignition enhances process stability, ongoing data collection and analysis through monitoring of energy consumption and silicon rods weight increase energy efficiency.
