摘要:
The invention relates to a semiconductor component, which can be produced in a simple, rapid, but nevertheless reliable manner and can be used in particular for power applications. The component comprises: a semiconductor chip (2, 12); a lower first primary electrode layer (3, 13) configured on a first side (2a) of the semiconductor chip (2, 12); a lower control electrode layer (4, 14) configured on said first side (2a); an isolation layer (5, 15), which partially covers the lower first primary electrode layer (3, 13) and is configured on the first side (2a) between the lower first primary electrode layer (3, 13) and the lower control electrode layer (4, 14); an upper first primary electrode layer (6, 16) configured on the lower first primary electrode layer (3, 13); an upper control electrode layer (7, 17), which is configured on the lower control electrode layer (4, 14) and the isolation layer (5, 15), extending over the isolation layer (5, 15) partly above the lower first primary electrode layer (3, 13); and a second primary electrode layer (9, 19) that is configured on a second side (2b) of the semiconductor chip (2, 12).
摘要:
The invention relates to a switched-mode power supply (10) for converting an electric input variable (Ue) into an output variable (Ua), said supply comprising at least one inductance (L), which can be switched against an achievement potential (3,5) or a reference potential (4,6) using several switches (a-d). The switching losses of the converter (10) can be substantially reduced if at least one switch (a-d) is only activated in a zero-voltage mode.
