Title (EN) POWER CONVERSION DEVICE
(FR) DISPOSITIF DE CONVERSION DE COURANT
(JA) 電力変換装置
Abstract:
(EN) Disclosed is a power conversion device wherein: a reactor (2), a single-phase inverter (300), and a single-phase converter (200) are connected in series between an alternating current power supply (1) and a smoothing capacitor (4); and power conversion is performed between an alternating current voltage (vac) of the alternating current power supply (1), and a direct current voltage (Vc1) of the smoothing capacitor (4). The power conversion device is provided with a control unit (100), which performs charging/discharging operations of a direct current capacitor (3) within one switching cycle (Tsw) of the single-phase capacitor (300), and which controls switching elements (5a-5d) of the single-phase inverter (300), and switching elements (6b, 6d) of the single-phase converter (200) such that the charging quantity and the discharging quantity of the direct current capacitor are equal to each other.
(FR) L'invention concerne un dispositif de conversion de courant comprenant un réacteur (2), un onduleur monophasé (300) et un convertisseur monophasé (200) qui sont connectés en série entre une alimentation électrique à courant alternatif (1) et un condensateur de lissage (4); et une conversion de courant est effectuée entre une tension alternative (vac) de l'alimentation en courant alternatif (1) et une tension continue (Vc1) du condensateur de lissage (4). Le dispositif de conversion de courant est pourvu d'une unité de commande (100) qui effectue des opérations de charge/décharge d'un condensateur à courant continu (3) dans un cycle de commutation (Tsw) du condensateur monophasé (300), et qui commande des éléments de commutation (5a-5d) de l'onduleur monophasé (300), et des éléments de commutation (6b, 6d) du convertisseur monophasé de sorte que la quantité de charge et la quantité de décharge du condensateur de courant continu sont égales.
(JA) 交流電源(1)と平滑コンデンサ(4)との間にリアクトル(2)と単相インバータ(300)と単相コンバータ(200)とを互いに直列に接続し、交流電源(1)の交流電圧(vac)と平滑コンデンサ(4)の直流電圧(Vc1)との間で電力変換を行う電力変換装置であって、単相インバータ(300)の1スイッチング周期(Tsw)内で直流コンデンサ(3)の充電および放電の動作を行い、かつ、その充電量と放電量とが等しくなるよう単相インバータ(300)のスイッチ素子(5a)~(5d)と単相コンバータ(200)のスイッチ素子(6b)、(6d)とを制御する制御部(100)を備えた。
