Title (EN) SYSTEMS AND METHODS FOR CHARGING AND DISCHARGING ACTIVE POWER LINK MODULES IN DIRECT CURRENT POWER SYSTEM
(FR) SYSTÈMES ET PROCÉDÉS DE CHARGE ET DE DÉCHARGE DE MODULES DE LIAISON DE PUISSANCE ACTIVE DANS UN SYSTÈME D'ALIMENTATION EN COURANT CONTINU
Abstract:
(EN) A modular power converter system includes a plurality of active power link modules (APLMs) coupled to each other, each APLM having a plurality of switching devices including first and second switching devices coupled to each other, and at least one first-type energy storage device (ESD) coupled in parallel with both of the first and second switching devices, the first-type ESD configured to induce a first direct current (DC) voltage. The system also includes a plurality of relays coupled to the first-type ESD, and a charge controller coupled to at least one APLM of the plurality of APLMs and coupled to at least one of an electrical power source and a discharge circuit. The charge controller is configured to alternately charge and discharge the first-type ESD in response to a plurality of switching states including switching states of the plurality of switching devices and the plurality of relays.
(FR) Un système de convertisseur de puissance modulaire comprend une pluralité de modules de liaison de puissance active (APLM) couplés les uns aux autres, chaque APLM ayant une pluralité de dispositifs de commutation comprenant des premier et second dispositifs de commutation couplés l'un à l'autre, et au moins un dispositif de stockage d'énergie (ESD) de premier type couplé en parallèle à la fois avec le premier et le second dispositif de commutation, l'ESD de premier type étant configuré pour induire une première tension continue. Le système comprend également une pluralité de relais couplés à l'ESD de premier type, et un contrôleur de charge couplé à au moins un APLM de la pluralité d'APLM et couplé à un bloc d'alimentation électrique et/ou à un circuit de décharge. Le contrôleur de charge est configuré pour charger et décharger en alternance l'ESD de premier type en réponse à une pluralité d'états de commutation comprenant des états de commutation de la pluralité de dispositifs de commutation et de la pluralité de relais.
