Abstract: front page image
(EN)A power conditioner (1) is provided with: a PV converter (10) having a capacitor (C12) connected to HDVC bus (2A, 3A), transforming a DC voltage, and smoothing the transformed DC voltage by the capacitor (C12); a bidirectional DC-DC converter (20) having a capacitor (C22) connected to the HDVC bus (2A, 3A) and smoothing the DC voltage input from the HDVC bus (2A, 3A) by the capacitor (C22); a DC-AC inverter (30) having a capacitor (C31) connected to the HDVC bus (2A, 3A) and smoothing the DC voltage output to the HDVC bus (2A, 3A) by the capacitor (C31); and a discharge circuit connected to the HDVC bus (2A, 3A) and comprising a switching element (S1) and a resistor (R4) for discharging the charge stored in the capacitors (C12, C22, C31). This provides a space-saving power conditioner.
(FR)L'invention concerne un conditionneur de puissance (1) comprenant : un convertisseur photovoltaïque (PV) (10) doté d'un condensateur (C12) relié à un bus HDVC (2A, 3A) transformant une tension CC et lissant la tension CC transformée à l'aide du condensateur (C12) ; un convertisseur CC-CC bidirectionnel (20) doté d'un condensateur (C22) relié au bus HDVC (2A, 3A) et lissant l'entrée de tension CC à partir du bus HDVC (2A, 3A) ; un inverseur CC-CA (30) doté d'un condensateur (C31) relié au bus HDVC (2A, 3A) et lissant la sortie de tension CC vers le bus HDVC (2A, 3A) à l'aide le bus ; et un circuit de décharge relié au bus HDVC (2A, 3A) et comprenant un élément de commutation (S1) et une résistance (R4) pour décharger la charge stockée dans les condensateurs (C12, C22, C31). On obtient ainsi un conditionneur de puissance à encombrement réduit.
(JA) パワーコンディショナ(1)は、HDVCバス(2A,3A)に接続されたキャパシタ(C12)を有し、直流電圧を変圧して、キャパシタ(C12)で平滑するPVコンバータ(10)と、HDVCバス(2A,3A)に接続されたキャパシタ(C22)を有し、HDVCバス(2A,3A)から入力される直流電圧をキャパシタ(C22)で平滑する双方向DC-DCコンバータ(20)と、HDVCバス(2A,3A)に接続されたキャパシタ(C31)を有し、HDVCバス(2A,3A)へ出力する直流電圧をキャパシタ(C31)で平滑するDC-ACインバータ(30)と、HDVCバス(2A,3A)に接続され、キャパシタ(C12,C22,C31)に蓄電された電荷を放電するスイッチ素子(S1)及び抵抗(R4)からなる放電回路とを備える。これにより、省スペース化を実現するパワーコンディショナを提供する。
