Claims (6)

1. Strömkälla, omfattande en transformator (M) med primär- och sekundärlindningar (N^, n2, N3), varvid i serie med primär-lindningen (N^) kopplats en elektronisk kopplare (SCR^; T), vilken öppnas och slutes med bestämd frekvens i och för ästadkom-mande av en pulserande primärström, och i serie med sekundärlind-ningen (N2) kopplats ätminstone ett likriktarelement (D-j) för ai string av en likriktad utgängsspänning (U3), känneteck-n a d av att sekundärkretsen utformats säsom en avstämd likriktare medelst en tili sekundärlindningen (N2) ansluten kondensator (C2)» vars värde valts sä, att sekundärlindningens (N2) Ström genom in-verkan av likriktarelementet (D3) avbrytes vid en tidpunkt da primär-lindningens (N^) ström är liten.
2. Strömkälla enligt patentkravet 1, vid vilken kopplaren pä primärsidan ästadkommits medelst en tyristor (SCR^) , kanne-tecknad av att sekundärsidans kondensator (C2) valts sä, att sekundärlindningens (N2) ström gär till noll nägot innan ty-ristorn erhäller sin kommuteringsström.
3. Strömkälla enligt patentkravet 2 för en televisionsmottagare, varvid den ifrägavarande trans forma torn (M) utgöres av en linjetrans-formator, kännetecknad av att mottagarens bildbe-lastning och 1judbelastning anslutits tili tvenne olika sekundärlindningar (N2/ N3) hos linjetransformatorn och att den avstämda likriktaren bildats med hjälp av 1judbelastningens sekundärlind-ning (N2).
4. Strömkälla enligt patentkravet 1, vid vilken kopplaren pä primärsidan ästadkommits medelst en transistor (T), kännetecknad av att transistorn medelst en frän sekundärkretsen tagen äterkoppling styrts att öppna vid en tidpunkt dä sekundär-
