Abstract: A transformer includes a transformer core, a first wire, which forms a first winding, and a second wire, which forms a second winding. The first and second windings are wound around the transformer core. A preformed insulation structure is arranged between the first and second winding and designed to space apart the second winding from the first winding and the transformer core. The preformed insulation structure further includes a first shell which at least partially encloses the transformer core with the first winding, and a second shell which at least partially encloses the transformer core with the first winding. The first and second shells are identical. One or more holes are defined in the first shell and the second shell. The one or more holes cover more than 10% of a surface of the preformed insulation structure.

Abstract: A semiconductor component has interface functions between the controller and the power components of power converters, suitable for gating semiconductor switches. In particular, the semiconductor component serves to gate IGBT and MOSFET power switches in low and medium performance three-phase bridge circuits and integrates signal processing (12), level conversion (16) and amplification (gate driver) (17), error recognition, such as short-circuit monitoring by means of VCE detection (19) and operating voltage monitoring (21) as well as error processing (15) for several power semiconductor switches. The advantages of this gating IC in comparison with hybrid or discrete solutions consist of the high integration density of various digital, analogue and driver functions which result in a reduction in the number of discrete components, which means a lower failure rate of the system and lower costs. Another important consideration is the improvement of switching characteristics thanks to monolithic integration.
