Abstract
The invention relates to a power supply arrangement, in particular for supplying power to thin silicon rods in a reactor for producing polysilicon with the Siemens process, with inputs (L1, L2, L3) for connection to a three-phase power grid, with outputs, grouped in three groups (A11-A13, A21-A24, A31-A33) of outputs for supplying power to loads connected to the outputs, in particular the thin silicon rods, with three groups (S1, S2, S3) of adjusting means for adjusting an electric voltage present at the outputs, and with three groups (U1, U2, U3) of switchover means for switching between a parallel connection and a series connection of the outputs in one of the groups (A11-A13, A21-A24, A31-A33) of outputs, wherein at least in one state of the power supply arrangement, each group (S1, S2, S3) of adjusting means is connected to a group of outputs (A11-A13, A21-A24, A31-A33) by way of a group of switchover means (U1, U2, U3).
