Title (EN) ELECTRICAL PULSE GENERATING MODULE WITH STORAGE CAPACITOR, FREEWHEELING DIODE AND TRANSFORMER RESET DURING CHARGING
(FR) MODULE DE GÉNÉRATION D'IMPULSIONS ÉLECTRIQUES AVEC CONDENSATEUR-MAGASIN, DIODE LIBRE ET RÉINITIALISATION DE TRANSFORMATEUR PENDANT LA CHARGE
Abstract:
(EN) An arrangement (100) is disclosed, comprising an electrical pulse generating module (10) configured to generate at least one electrical pulse, and a transformer (20) electrically connected to the electrical pulse generating module (10). The electrical pulse generating module (10) comprises an electrical energy storage module (40) that can be charged or discharged, and a switch unit (50) controllably switchable between at least a conducting state and a non-conducting state. When the switch unit (50) is switched into the non-conducting state, a power supply (30) charges the electrical energy storage module (40) by way of a charging current. When the switch unit (50) is switched into the conducting state, the electrical energy storage module (40) is discharged to create an electrical pulse to be received by the transformer (20). The electrical pulse generating module (10) comprises a flyback protection unit (60) configured to protect the switch unit (50) against flyback upon the switch unit (50) being switched into the non-conducting state. The flyback protection unit (60) forms a current path (65) that bypasses the transformer (20), and is configured such that a relation between the voltage drop across the flyback protection unit (60) for the charging current and the voltage drop across the transformer (20) for the charging current is such so as to cause the charging current to be directed via the transformer (20) at least to some extent.
(FR) L'invention concerne un agencement (100), comprenant un module de génération d'impulsions électriques (10) configuré pour générer au moins une impulsion électrique, et un transformateur (20) connecté électriquement au module de génération d'impulsions électriques (10). Le module de génération d'impulsions électriques (10) comprend un module de stockage d'énergie électrique (40) qui peut être chargé ou déchargé, et une unité de commutation (50) commutable de manière contrôlable entre au moins un état conducteur et un état non conducteur. Lorsque l'unité de commutation (50) est commutée dans l'état non conducteur, une alimentation électrique (30) charge le module de stockage d'énergie électrique (40) au moyen d'un courant de charge. Lorsque l'unité de commutation (50) est commutée dans l'état conducteur, le module de stockage d'énergie électrique (40) est déchargé pour créer une impulsion électrique devant être reçue par le transformateur (20). Le module de génération d'impulsions électriques (10) comprend une unité de protection de retour du spot (60) configurée pour protéger l'unité de commutation (50) contre le retour du spot sur l'unité de commutation (50) qui est commutée dans l'état non conducteur. L'unité de protection de retour du spot (60) forme un trajet de courant (65) qui contourne le transformateur (20), et est configurée de telle sorte qu'une relation entre la chute de tension à travers l'unité de protection de retour du spot (60) pour le courant de charge et la chute de tension à travers le transformateur (20) pour le courant de charge est conçue de manière à amener le courant de charge à être dirigé par l'intermédiaire du transformateur (20) au moins dans une certaine mesure.
