Throughout the high-tech polysilicon value chain, AEG Power Solutions has been a leading supplier of superior high-current power supplies for many years. AEG power controllers are wellestablished in the fields of creating silicon ingots formed from monocrystalline silicon crystals (Czochralsky process) and of creating multicrystals using the ingot casting process.

A new focus of applications for thyristor power controllers and systems is sapphire crystal growing (e.g. according to the Kyropoulos or Czochralsky processes).

Thyrobox Sa - Description

Power Supply, Sapphire Crystal Growing


Due to the increasing demand for efficient LED lamps as well as for further applications (such as sapphire-windows and -glasses) the sapphire manufacturing process plays an increasingly signifi cant role. Therefore the relevance of the sapphire manufacturing process and the expectations regarding yields, quality and profitability of the production continue to rise. An important parameter of sapphire production is the stability of the batch process. Herewith essential specifications have been set for all process related components and systems which is especially important for critical procedural or large volume charges.


Profitability, reliability, and reproducibility are synonymous with competitiveness. Capabilities to fulfill these key properties are a must-have for any power supply. Since every crystal growing method has its own unique technical specialties, AEG Power Solutions offers custom solutions based on the specific requirements of the electric power supply.
