Patent ID: 8441146

Claim:
A current supply arrangement for a reactor for producing polysilicon, the arrangement comprises a first current supply device ( 10 ), a second power supply device ( 20 ) including at least two AC current regulators ( 22 ) and a voltage sequence controller ( 23 ) for controlling the AC current regulators ( 22 ), a terminal group including at least two terminals ( 31 , 32 , 33 , 34 , 35 ) for connecting at least one load ( 41 , 42 , 43 , 44 ), wherein a first terminal ( 31 ) is connected directly without an interconnected switch, with an output terminal ( 24 ) of the second current supply device ( 20 ), and including a first switching group associated with the terminal group, with switches for connecting and disconnecting the terminals ( 31 , 32 , 33 , 34 , 35 ) of the terminal group with or from output terminals ( 11 , 12 , 13 , 14 , 15 ) of the first current supply device ( 10 ), wherein the current supply arrangement comprises additional second current supply devices ( 20 ) including at least two AC current regulators ( 22 ) and a voltage sequence controller ( 23 ) for controlling the AC current regulators ( 22 ), additional terminal groups comprising at least two terminals ( 31 , 32 , 33 , 34 , 35 ) for connecting at least one load ( 41 , 42 , 43 , 44 ), wherein the terminals ( 31 , 32 , 33 , 34 , 35 ) of each terminal group a first terminal ( 31 ) is connected directly, without an interconnected switch, with an output terminal ( 24 ) of one of the additional second current supply devices ( 20 ), and additional first switching groups, each associated with a corresponding one of the additional terminal groups, with first switches ( 51 , 52 , 53 , 54 , 55 ) for connecting and disconnecting the terminals ( 31 , 32 , 33 , 34 , 35 ) of the terminal group with or from the output terminals ( 11 , 12 , 13 , 14 , 15 ) of the first current supply device ( 10 ).
