Title (EN) VOLTAGE CONVERSION METHOD
(FR) PROCEDE DE CONVERSION DE LA TENSION
Abstract: front page image
(EN)Voltage conversion method specially feasible for the transformation of low voltages to high voltages by means of a switching converter. The method according to the present invention eliminates the current transients (B) through the switching unit (S), which is controlled in such a way that the time period (tf) during which the switching unit (S) is in its off-state is made to have a duration such that the resonance voltage (Du) on the transformer windings always has a predetermined phase, when said switching unit (S) is triggered to change to its conduction state. Voltage conversion according to the invention has high efficiency and causes little radio-frequency interference.
(FR)Procede de conversion de la tension specialement applicable a la transformation d"une basse tension en haute tension a l"aide d"un convertisseur de commutation. Le present procede elimine les courants transitoires (B) dans l"unite de commutation (S) qui est commandee de telle maniere que la periode de temps (tf) pendant laquelle l"unite de commutation (S) se trouve dans son etat debranche ait une duree telle que la tension de resonance (Du) sur les enroulements transformateurs ait toujours une phase predeterminee, lorsque ladite unite de commutation (S) est declenchee pour changer vers son etat de conduction. La presente conversion de tension est tres efficace et provoque peu d"interference de radiofrequence.
