Abstract

A driver stage, especially for a power switch transistor (210) comprises an auxiliary power supply (202), a current regulator (212) for the base current of the switch transistor and an overdrive, preferably with a logic processor (218). A shell-type transformer (230) having a ferromagnetic core and at least one primary and one secondary coil is used as a switching voltage and power transformer for the positive base current. Its core is as gap-free as possible and at least one coil has the form of a foil. The primary and secondary coils of the transformer are wound on each other, with an intermediate insulating layer, forming cylindrical coils. Each current-conducting part-winding of the primary coil adjoins a current-conducting part-winding of the secondary coil.
