Title (EN) SOLAR POWER SYSTEM AND CONVERTER
(FR) SYSTÈME À ÉNERGIE SOLAIRE ET CONVERTISSEUR
(JA) 太陽光発電システム及び変換器
Abstract:
(EN) Provided is a technology that can suppress a reduction of performance of a solar cell due to PID. A converter is connected between a solar cell and an inverter for converting direct current power output from the solar cell to alternating current, and the ground potential of the negative electrode of the solar cell is made higher than the ground potential of the negative electrode of the inverter when direct current power generated by the solar cell is output to the inverter side. For example, the ground potential of the negative electrode of the solar cell is set to 0 V or more without commonizing the negative electrode of the solar cell and the negative electrode of the inverter.
(FR) L'invention concerne une technologie permettant de supprimer une détérioration des performances d'une photopile, provoquée par un PID. Un convertisseur est connecté entre une photopile et un onduleur pour convertir un courant continu fourni par la photopile en courant alternatif, et le potentiel de masse de l'électrode négative de la photopile est rendu plus élevé que le potentiel de masse de l'électrode négative de l'onduleur lorsqu'un courant continu produit par la photopile est fourni au côté onduleur. Par exemple, le potentiel de masse de l'électrode négative de la photopile est réglé au minimum à 0 V sans mettre en commun l'électrode négative de la photopile et l'électrode négative de l'onduleur.
(JA) PIDによる太陽電池の性能低下を抑制できる技術を提供する。変換器が、太陽電池と、当該太陽電池から出力される直流電力を交流に変換するインバータとの間に接続され、前記太陽電池で発電された直流電力を前記インバータ側へ出力する際、前記太陽電池の負極の対地電位を前記インバータの負極の対地電位よりも高くする。例えば、太陽電池の負極とインバータの負極をコモン化せず、太陽電池における負極の対地電位を0V以上とする。
