Power supply systems for the production of polysilicon

Used successfully worldwide, Thyrobox power supply systems are synonymous with utmost reliability and repeatability in the polysilicon production process.

As global market leader in the field of power supplies for polysilicon production, AEG Power Solutions provide custom solutions that are tailor-made for the polysilicon process. Owing to their state-of-the-art AC technology, AEG’s Thyrobox power supply systems are extremely energy-efficient and reliable as compared with other technologies.

Typical Thyrobox applications in polysilicon production include power supplies for the direct heating of polysilicon rods in the D reactor, also called deposition reactor, and for the direct heating of graphite elements in the H reactor (STC-TCS converter).
