Used successfully worldwide, powerbox 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, ALFA Power Solutions provide custom solutions that are tailor-made for the polysilicon process. Owing to their state-of-the-art AC technology, ALFA’s powerbox power supply systems are extremely energy-efficient and reliable as compared with other technologies.
Typical powerbox 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).
The illustration depicts different deposition reactor designs.
powerbox power supply systems meet the complex demands of both D and H reactors. The following illustration shows standard power supplies currently in use.
powerbox M | D-Reaktor | Modular systems for medium-voltage ignition, pre-heating and process heating for the CVD deposition process in reactors having 12, 18, 24 and 27-rod pairs |
powerbox MV-I | D-Reaktor | Power supply system for medium-voltage ignition of silicon rod pairs as a add-on for existing powerbox VSC power supply systems |
powerbox VSC-C | H-Reaktor | Power supply system for H reactors with multi-level VSC circuits |
powerbox M for 24 pairs of rods
W x H x D: 4400 x 2200 x 1600[mm]
The illustration shows a powerbox M for a 24-pair CVD reactor. Features include a medium-voltage ignition for all rods in the reactor and power supply for the CVD process.
All powerbox power supply systems from ALFA Power Solutions worldwide are installed and maintained by a team of well-qualified service technicians having on-site experience with the reactor power supplies used in the production of polysilicon.
