Title (EN) INVERTER DEVICE
(FR) DISPOSITIF ONDULEUR
(JA) インバータ装置
Abstract:
(EN) Provided is a serial multiplex inverter device (1) in which single phase output inverter cells (2) (U1-U6, V1-V6, W1-W6) each receiving AC power via a transformer (Tr) are connected in series in a multi-stage manner on a per-phase basis to form respective U-phase, V-phase, and W-phase and one ends of the series connections of the respective phases are connected with each other at a neutral point (N). Current detectors (HCT) are disposed in wires (3) leading from the inverter cells (U1, V1, W1) of a first stage to the neutral point (N), respectively. The neutral point (N) is connected through a resistor (R) to the ground. Accordingly, the potential of the wires (3) is low, so that the current detectors (HCT) are those conforming to a low withstand voltage specification.
(FR) L'invention concerne un dispositif onduleur à multiplexage série (1) dans lequel des cellules d'onduleur à sortie monophasée (2) (U1-U6, V1-V6, W1-W6) qui reçoivent chacune une puissance CA par l'intermédiaire d'un transformateur (Tr) sont connectées en série de manière étagée sur une base par phase de façon à former une phase U, une phase V et une phase W respectives, une extrémité des connexions en série des phases respectives étant connectées entre elles au niveau d'un point neutre (N). Des détecteurs de courant (HCT) sont disposés dans des fils (3) reliant les cellules d'onduleur (U1, V1, W1) d'un premier étage au point neutre (N), respectivement. Le point neutre (N) est relié à la masse par l'intermédiaire d'une résistance (R). Ainsi, le potentiel des fils (3) est faible, de manière que les détecteurs de courant (HCT) soient conformes à une spécification de tension de tenue faible.
(JA) 直列多重インバータ装置(1)は、トランス(Tr)を介して交流電力がそれぞれ入力される単相出力インバータセル(2)(U1~U6,V1~V6,W1~W6)を各相毎に多段直列に接続してU相、V相、W相の各々を構成してあり、これらの各相の直列接続の一端が中性点(N)において互いに接続されている。1段目のインバータセル(U1,V1,W1)から中性点(N)に至る配線(3)に、それぞれ電流検出器(HCT)が配置されている。中性点(N)は抵抗(R)を介して接地されている。従って、配線(3)は電位が低く、電流検出器(HCT)は、低耐圧仕様のものである。
