Abstract
A push-pull converter configured to convert an input voltage to an output voltage according to a transfer ratio is provided. The push-pull converter comprises a transformer, a first and a second switch transistor arranged to operatively provide the input voltage to the transformer such that the transfer ratio is obtainable, a first and a second rectification transistor arranged to operatively receive a first and a second part, respectively, of the output voltage from the transformer such that the transfer ratio is obtainable. The push-pull converter is further configured to synchronously operate the first switch transistor and the first rectification transistor, synchronously operate the second switch transistor and the second rectification transistor, and operate the first and second switch transistors 180 degrees out of phase with respect to each other.
