Abstract

Invenţia se referă la electrotehnică şi este destinată pentru realizarea convertizoarelor de tensiune de mare capacitate cu cvasirezonanţă , reglabile, cu aplicare diversă, şi anume pentru staţiile de protecţie catodică, care funcţionează la temperaturi ridicate cu răcire naturală, convertizoarele de sudură, instalaţiile de încălzire inductivă.Convertizorul de tensiune continuă cu cvasirezonanţă conţine un suport semipunte cu două tranzistoare (1, 2), colectorul unui tranzistor (1) este conectat la o bornă a bobinelor primare (4-1, 4-2), unite consecutiv în sens contrar, a unui transformator de ieşire (4), cu o inductivitate reciproca de disipare ridicată de o valoare prestabilită, a doua bornă a cărora este conectată la o bornă a unei surse de alimentare (3), iar emiterul celui de-al doilea tranzistor (2) este conectat la a doua bornă a sursei de alimentare (3). Convertizorul mai conţine un condensator de rezonanţă (5), o bornă a căruia este conectată la borna medie a suportului semipunte, iar cea de-a doua - la borna comună a bobinelor primare (4-1, 4-2) a transformatorului de ieşire (4), ieşirile bobinelor secundare ale căruia, executate cu o inductivitate de o valoare prestabilită, sunt conectate prin nişte redresoare (6-1, 6-2) la o sarcină comună (7).
