Abstract
A current supply arrangement for, e.g., producing polysilicon, with a first current supply device and a second power supply device, including two AC current regulators and a voltage sequence controller for controlling the AC current regulators, with a terminal group having two terminals for connecting a load. A terminals is connected directly, i.e., without an interconnected switch, with an output terminal of the second current supply device, and with a first switching group associated with the terminal group, with switches for connecting and disconnecting the terminals of the terminal group with or from output terminals of the first current supply device. The current supply arrangement also includes an additional current supply device having two AC current regulators and a voltage sequence controller for controlling the AC current regulators, additional terminal groups comprising two terminals for connecting one load.
