Abstract

L'invention concerne un circuit onduleur comportant deux transistors de commutation. Le circuit est caractérisé en ce qu'il comprend un transformateur de courant saturable 14 connecté entre les jonctions base-émetteur des transistors 12, 13 et servant à fournir des signaux intermittents de réaction positive pour produire une mise en conduction alternée des transistors et un transformateur de courant non saturable 15 également connecté entre les jonctions base-émetteur des transistors et produisant des signaux intermittents de réaction négative pour bloquer rapidement un transistor conducteur afin de faire passer un courant alternatif dans une charge reliée au circuit. Application aux dispositifs d'alimentation électrique.
