Abstract
Abstract A current supply installation is disclosed which comprises at least two voltage-controlled current supply devices connected in parallel at an output side without decoupling. In each of the current supply devices, a compound voltage value is formed by a first voltage proportional to a no-load voltage and a voltage proportional to an output voltage of the respective current supply device. This compound voltage value is used a the basis for an actul value for voltage control in each of the current supply devices.
