Title
(EN) SWITCHED MODE POWER SUPPLY
(FR) ALIMENTATION ELECTRIQUE A MODE COMMUTE
Abstract
(EN)
A controller for supplying a switching signal to a switched mode power supply, includes a sinusoidal-like wave generator, and circuitry for selectively shifting a dc level in the sinusoidal-like wave whereby a duty cycle of the sinusoidal-like wave at a predetermined threshold level, corresponding to a turn-on level of a power switch in the switched mode power supply, is effectively controlled.
(FR)
Un contrôleur servant à délivrer un signal de commutation à une alimentation électrique à mode commuté comprend un onduleur quasi sinusoïdal et un circuit prévu pour déphaser de manière sélective un niveau de courant continu dans l'onde quasi sinusoïdale. Au moyen de ce contrôleur, un rapport cyclique de l'onde quasi sinusoïdale à un niveau de seuil prédéterminé, correspondant à un niveau d'enclenchement du commutateur électrique de l'alimentation à mode commuté, est effectivement commandé.
