Abstract

Circuit convertisseur à modulation par impulsions de largeur variable pour la transformation d'une première tension continue en une seconde tension, où la seconde tension est régulée par le circuit convertisseur. Le circuit comprend un circuit à horloge, un circuit à modulation par impulsions de largeur variable asservis. L'horloge fournit un train d'impulsions rectangulaires à chacun des n + 1 conducteurs, une impulsion seulement se produisant sur l'un des conducteurs. Le modulateur principal est sensible au train d'impulsions de l'un des n + 1 conducteurs et à un signal de réaction indicatif de la seconde tension; il commande le débit de courant, dû à la première tension, dans une partie d'un enroulement primaire d'un transformateur. Chaque circuit asservi est sensible au train d'impulsions des n + 1 conducteurs et à un signal de sortie basé sur le signal de réaction, indicatif de la seconde tension, et sur la différence entre charges des circuits modulateurs principal et asservis. Chaque circuit modulateur asservi commande le courant, dû à la première tension continue, dans une partie de l'enroulement primaire d'un transformateur. Application aux alimentations de puissance.Variable width pulse modulation converter circuit for converting a first DC voltage into a second voltage, where the second voltage is regulated by the converter circuit. The circuit comprises a clock circuit, a servo-controlled variable width pulse modulation circuit. The clock supplies a train of rectangular pulses to each of the n + 1 conductors, with only one pulse occurring on one of the conductors. The main modulator is responsive to the pulse train of one of the n + 1 conductors and to a feedback signal indicative of the second voltage; it controls the current flow, due to the first voltage, in part of a primary winding of a transformer. Each slave circuit is responsive to the pulse train of the n + 1 conductors and to an output signal based on the feedback signal, indicative of the second voltage, and on the difference between the loads of the main and slave modulator circuits. Each servo modulator circuit controls the current, due to the first DC voltage, in a portion of the primary winding of a transformer. Application to power supplies.
