(FR) DISPOSITIF ONDULEUR
Abstract
(EN)
An inverter apparatus is provided such that it can limit the inrush current to a smoothing capacitor of a converter at the instant of connection to AC power line. The inverter apparatus comprises a converter (3); an inverter (4); a first smoothing capacitor (12) between positive and negative buses that connect the output of the converter and the inputs of the inverter; a first resistor (14) connected in either the positive or negative bus between the first smoothing capacitors (12) and the converter (3); and first switch means (16) connected in parallel with the first resistor. A second smoothing capacitor (11) connected in series with a parallel circuit of a second resistor (13) and second switch means (15) is connected between the positive and negative buses between the converter (3) and the switch means (16).

L'invention concerne un dispositif onduleur conçu pour pouvoir limiter le courant d'appel vers un condensateur de lissage d'un convertisseur, au moment de la connexion à la ligne de puissance en courant alternatif. Ce dispositif onduleur comprend un convertisseur (3), un onduleur (4), un premier condensateur de lissage (12) monté entre un bus positif et un bus négatif, lesquels bus connectent la sortie du convertisseur et les entrées de l'onduleur, une première résistance (14) connectée soit au bus positif, soit au but négatif, entre les premiers condensateurs de lissage (12) et le convertisseur (3), ainsi que des moyens de commutation (16) connectés en parallèle avec la première résistance. Un second condensateur de lissage (11) connecté en série à un circuit parallèle d'une seconde résistance (13) et de seconds moyens de commutation (15) est connecté entre les bus positif et négatif, entre le convertisseur et les moyens de commutation (16).
