An output voltage (uA) is formed in response to a start signal (Ss), as a function of a transformer voltage that is determined recently before the output current exceeds the permissible value and as a function of magnetic fluxes (phi1, phi2). An Independent claim is also included for an apparatus for carrying out a method of operating a transformer from a drivable voltage source.",
