Abstract

A circuit for a semiconductor switching element including a transformer. One embodiment provides a first voltage supply circuit having a first oscillator. A first transformer is connected downstream of the first oscillator. A first accumulation circuit for providing a first supply voltage is connected downstream of the first transformer. A driver circuit having input terminals for feeding in the first supply voltage and having output terminals for providing a drive voltage for the semiconductor switching element, designed to generate the drive voltage for the semiconductor switching element at least from the first supply voltage.
