Abstract

An example relates to a method for operating a converter comprising a primary side of a transformer and a secondary side of the transformer, wherein a switching element is used for conveying energy from the primary side to the secondary side, the method comprising (i) determining a voltage drop across the primary side of the transformer; (ii) determining at least one additional voltage drop across at least one component of the converter's primary side; and (iii) determining an input voltage at the converter via the voltage drops.
