<P>PROBLEM TO BE SOLVED: To provide a power supply comprising means for increasing a voltage. <P>SOLUTION: The invention relates to a power supply comprising: a first transformer (T1) having at least two secondary-side taps for a secondary-side external conductor potential and a tap for a secondary-side neutral conductor potential, where a rated voltage of the first transformer drops in standard operation of the first transformer between a first of the taps for the secondary-side external conductor potential and the tap for the secondary-side neutral conductor potential; and two power controllers (V1, V2) connecting the taps for the secondary-side external conductor potential with an external conductor terminal of an output of the power supply. The power supply on the secondary side of the first transformer (T1) comprises means (T2) for increasing the voltage beyond the rated voltage. <P>COPYRIGHT: (C)2013,JPO&INPIT |
