Abstract: front page image
(EN)This power conversion device is provided with a power source (1), a boosting means (a reactor (21) and a switch (22)) for boosting by switching control the voltage supplied from the power source (1), a smoothing circuit (3) for smoothing the voltage output from the boosting means, a rectifier (23) disposed between the booster means and the smoothing circuit (3) for preventing the reverse flow of current to the boosting means, and a commutation means (4) which, connected in parallel to the rectifier (23), reverses the current flowing to the rectifier (23) to flow towards said commutation means (4).
(FR)L'invention concerne un dispositif de conversion de puissance comprenant une source d'alimentation (1), un moyen d'amplification (un réacteur (21) et un commutateur (22)) afin d'amplifier par commande de commutation la tension fournie par la source d'alimentation (1), un circuit de lissage (3) pour lisser la sortie de tension venant du moyen d'amplification, un redresseur (23) disposé entre le moyen d'amplification et le circuit de lissage (3) afin d'empêcher le flux inverse de courant vers le moyen d'amplification, et un moyen de commutation (4) qui est connecté en parallèle au redresseur (23) et qui inverse le courant circulant vers le redresseur (23) pour qu'il circule vers ledit moyen de commutation (4).
(JA) 本発明にかかる電力変換装置は、電源(1)と、電源(1)から供給される電圧をスイッチング制御により昇圧する昇圧手段(リアクトル(21),スイッチ(22))と、昇圧手段からの出力電圧を平滑する平滑回路(3)と、昇圧手段と平滑回路(3)の間に配置され、昇圧手段側への電流逆流を防止する整流器(23)と、整流器(23)に並列に接続され、整流器(23)に流れていた電流を自身側に転流させる転流手段(4)と、を備えている。
