Title (EN) INVERTER HAVING EXTENDED LIFETIME DC-LINK CAPACITORS
(FR) ONDULEUR COMPORTANT DES CONDENSATEURS DE LIAISON CC AYANT UNE PLUS GRANDE DURÉE DE VIE
Abstract:
(EN) An inverter having extended lifetime DC-link capacitors for use with a DC power source such as a photovoltaic panel is described. The inverter uses a plurality of switchable capacitors to control the voltage across the capacitors. The expected lifetime of the capacitors can be extended by disconnecting unnecessary capacitors from a voltage. The capacitors may be periodically connected to a voltage in order to maintain an oxide dielectric layer of the capacitor.
(FR) L'invention concerne un onduleur comportant des condensateurs de liaison CC ayant une plus grande durée de vie que l'on utilise avec une source d'alimentation CC comme un panneau photovoltaïque. L'onduleur utilise plusieurs condensateurs commutables afin de commander la tension dans les condensateurs. La durée de vie escomptée des condensateurs peut être allongée en déconnectant les condensateurs inutiles de la tension. Les condensateurs peuvent être connectés périodiquement à une tension afin d'entretenir une couche diélectrique oxyde du condensateur.
