Abstract
A system for the production of a polycrystalline silicon product is disclosed. The system includes a reaction chamber, a susceptor, an induction unit, and a plurality of energy sources. The reaction chamber has a reactor wall, and the susceptor encircles the reactor wall. The induction heater surrounds the susceptor, and has multiple induction coils for producing heat in the susceptor. The coils are grouped into a plurality of zones. The plurality of energy sources supply electric current to the coils. Each energy source is connected with the coils of at least one zone.
