Abstract
(EN)
This power conversion device is provided with: a bridge circuit (3) that is equipped with at least one or more legs formed by connecting in series switching elements each having a diode connected in parallel and converts the AC voltage output from an AC power supply (1) to a DC voltage; and a reactor (2) having one end connected to the AC power supply (1) and the other end connected to the connection point of the two switching elements of the leg. The short-circuit current flowing when the bridge circuit (3) is short-circuited flows, in accordance with a polarity of the AC power supply (1), in the order from the reactor (2) to a switching element of the leg, which flows current in a direction opposite to the forward direction of the diode connected in parallel, or in the order from a switching element of the leg, which flows current in a direction opposite to the forward direction of the diode connected in parallel, to the reactor (2).

Ce dispositif de conversion de puissance est pourvu : d'un circuit en pont (3) qui est équipé d'au moins une ou plusieurs branches formées par connexion en série d'éléments de commutation ayant chacun une diode connectée en parallèle et qui convertit la sortie en tension alternative en provenance d'une alimentation en courant alternatif (1) à une tension continue ; et une bobine de réactance (2) dont une extrémité est connectée à l'alimentation en courant alternatif (1) et dont l'autre extrémité est connectée au point de connexion des deux éléments de commutation de la branche. Le courant de court-circuit s'écoulant lorsque le circuit en pont (3) est court-circuité s'écoule, en fonction d'une polarité de l'alimentation en courant alternatif (1), dans l'ordre à partir de la bobine de réactance (2) jusqu'à un élément de commutation de la branche, qui fait circuler le courant dans une direction opposée à la direction avant de la diode connectée en parallèle, ou dans l'ordre à partir d'un élément de commutation de la branche, qui fait circuler le courant dans une direction opposée à la direction avant de la diode connectée en parallèle, jusqu'à la bobine de réactance (2).
