Abstract
L'invention concerne un circuit de commande du courant dans une bobine. Ce circuit comporte deux circuits de commutation comprenant chacun un transistor et une diode ainsi qu'un circuit résonnant constitué par une bobine et un condensateur. Un condensateur de charge est connecté dans un circuit commun à ces deux circuits de commutation. Des signaux déphasés commandent les deux transistors de manière à établir une tension déterminée aux bornes de ce condensateur et par conséquent, un courant déterminé dans l'une des bobines. L'invention s'applique notamment au circuit de déviation horizontale d'un récepteur de télévision, pour corriger la distorsion en coussin.
