Claims (8)

1. Avböjningskrets, som innehäller: en avböjningslindning; en svepomkopplare med en styrelektrod och vilken som ledande alst-rar en svepström i avböjningslindningen; en till avböjningslind-ningen kopplad svepätergängskapasitans, som bildar en första reso-nanskrets (32, 34) under ett svepätergängsintervall när svepomkopp-laren är oledande; en första resonanskrets; en belastningskrets, vilken är kopplad till den första resonanskretsen, vilken överför energi till den här belastningskretsen under svepätergänsinterval-let; och en matningsenergikälla; en andra resonanskrets (26) som innehäller en andra kondensator (28), vilken krets mottagar energi frän nämnda kalla (-VQ), lagrar den och matar energi till den första resonanskretsen (32, 34) och bildar en Ström, som motstar strömmen som flyter i svepomkopplaren under slutet av svepintervallet; och en till den andra resonanskretsen (26) kopplad andra omkopplings-anordning (24) , som alstrar en resonansströmoscillation i den andra resonanskretsen och börjar äterfängsintervallet; känneteck-n a d därav, att den andra omkopplingsanordningen (24) börjar nämnda resonansoscillation i den andra resonanskretsen (26) under äter-gängsintervallen, att tili den andra kondensatorn (28) lagrad energi överförs tili den första resonanskretsen (32, 34) förrän en po-laritetsomkastning uppträder i den andra kondensatorn (28) under resonansströmoscillationen, och att i den andra resonanskretsen (26) under den tiden, när energi tas frän källan (B+, B-), flytande strömmen (ig) t ästadkommer nedgäng av strömmen (1^3) i svepomkopplaren (30) i närheten av slutet av svepintervallet (t1 - t^) för att mins-ka den maximala omkopplingsströmmen (+1^).
2. Krets enligt patentkravet 1, kännetecknad därav, att en svepätergänstransformator (45, 145) ingär i den andra belastningskretsen.
3. Krets enligt patentkravet 1 eller 2, kännetecknad därav, att strömmen som flyter i den andra resonanskretsen (26) kommuterar den andra omkopplingsanordningen (24) .
4. Krets enligt patentkraven 1-3, kännetecknad därav, att matningsenergikällan är en strömkälla (-VQ, 23; +Vg, 123).
5. Krets enligt patentkravet 4, kännetecknad därav, att nämnda strömkälla innefattar en induktans (23, 123) som II
