57AbstractABEine Mehrlagen-Leiterplatte für Schaltnetzteile besteht aus zwei Trägerplatten 1 bzw. 3, auf denen jeweils Signalleiter-Ebenen 2 bzw. 4 ausgebildet sind. Eine dazwischen angeordnete Schutzleiter-Ebene 6 dient dem direkten Anschluß von Entstörelementen 10 an den Schutzleiter PE und schirmt gleichzeitig die elektronischen Bauelemente 9 der Schaltung ab.$A Die vorgeschlagene Mehrlagen-Leiterplatte erlaubt den Aufbau eines äußerst kompakten Schaltnetzteils, das auch ohne schirmendes Metallgehäuse höchsten Anforderungen hinsichtlich Störstrahlungsfreiheit gerecht wird.
