Abstract

The invention relates to a power supply assembly. The arrangement has a main transformer (T1) having two secondary-side taps for secondary-side phase conductor potential and a tap for secondary-side neutral conductor potential. The rated voltage (UB) drops between the taps for phase conductor potential and neutral conductor potential in standard operation of main transformer. The power controllers (V1,V2) connect the taps for phase conductor potential with a phase conductor terminal of output of arrangement. A circuit device on secondary side of main transformer has auto transformer (T2) for increasing voltage above rated voltage.

Description

technical field [0001] The invention relates to a power supply arrangement comprising a first transformer with at least two secondary-side taps for the secondary-side outer conductor potential and a tap for the secondary-side neutral potential and two power regulators , wherein a rated voltage is generated between one of the first taps for the secondary side external line potential and the tap for the secondary side neutral line potential in the rated operating state of the first transformer for the secondary side external line potential The tap is connected via the power regulator to a first connection of an output of the power supply unit. Background technique [0002] Power supply devices of this type are known from numerous patent documents and published publications of patent applications by the applicant or a previous assignee of the applicant. Some power devices of this type are also described in some textbooks, for example in 2009 G. K. Dubey, S. R. Doradla, A. ...
