Abstract: Le transformateur triphasé T3 est alimenté par un secteur triphasé V1, V2, V3, les phases V1, V2 étant coupées par des interrupteurs I1, I2 à thyristors tête-bêche, tandis que la phase V3 est reliée directement au transformateur. Les interrupteurs I1, I2 sont prévus pour être passants en onde entière. Pour cela, en régime établi, le début de chaque train d'ondes est obtenu par fermeture dans un ordre constant du premier interrupteur I1 ou I2 à un instant proche du passage à zéro de la tension appliquée, et en alternant d'un train d'ondes au suivant le signe de la dérivée de cette tension présente à ses bornes immédiatement avant sa fermeture, et du deuxième interrupteur I2 ou I1 environ 90 degrés après le premier. La durée d'un train d'ondes est de 570 degrés plus un nombre entier ou nul de périodes. Ceci est assuré par comptage des commandes d'amorçage par les transformateurs d'impulsion T1 et T2 pilotés par les monostables U16 et U19, le comptage étant effectué par le compteur U17.
