Patent attributes
The invention focuses on a voltage transformer (VT) that includes at least two transformer stages (VT I, VT II), each of them with an input connection and to each of which an input subvoltage UEI, UEII is attached and added together they form an input voltage UE, and each of them with an outlet connection where an output subvoltage UAI, UAII is attached to each outlet, the total forming an output voltage UA. In order to prove that a concentration of electrical power of several stages is possible with or without a transformer, as well as to improve the efficiency and lower the cost, it is planned to attach a positive output subvoltage UAI at the first outlet of the transformer stage (VT I) with reference to a ground potential (P) and to attach a negative output subvoltage UAII with reference to this ground potential (P) at the outlet of the second transformer stage (VT II), whereby the sum of the individual output subvoltages UAI, UAII is the output voltage UA.
