Abstract:
(EN) Provided is a highly reliable power conversion device. This power conversion device (30) is equipped with: a power conversion unit (31), which has upper arm switching elements (S1, S3, and S5) connected to the positive side of a smoothing capacitor (C) and lower arm switching elements (S2, S4, and S6) connected to the negative side of the smoothing capacitor (C), and which converts DC voltage applied from the smoothing capacitor (C) to a drive voltage for a motor (11a); and a control unit (33) which, when the motor (11a) is stopped, alternately repeats a first state in which at least two of the switching elements of one of the arms, that is, the upper arm or the lower arm, are turned on, and the other switching elements are turned off, and a second state in which the upper arm switching elements and the lower arm switching elements (S1-S6) are turned off.
(FR) L'invention concerne un dispositif de conversion de puissance extrêmement fiable. Ce dispositif de conversion de puissance (30) est équipé : d'une unité de conversion de puissance (31), qui a des éléments de commutation de bras supérieur (S1, S3 et S5) connectés au côté positif d'un condensateur de lissage (C) et des éléments de commutation de bras inférieur (S2, S4 et S6) connectés au côté négatif du condensateur de lissage (C), et qui convertit une tension continue appliquée par le condensateur de lissage (C) en une tension d'attaque pour un moteur (11a) ; et d'une unité de commande (33) qui, lorsque le moteur (11a) est arrêté, répète en alternance un premier état dans lequel au moins deux des éléments de commutation de l'un des bras, c'est-à-dire le bras supérieur ou le bras inférieur, sont activés, et les autres éléments de commutation sont éteints, et un second état dans lequel les éléments de commutation de bras supérieur et les éléments de commutation de bras inférieur (S1-S6) sont éteints.
(JA) 信頼性の高い電力変換装置等を提供する。電力変換装置(30)は、平滑キャパシタ(C)の正側に接続される上アームのスイッチング素子(S1,S3,S5)を有するとともに、平滑キャパシタ(C)の負側に接続される下アームのスイッチング素子(S2,S4,S6)を有し、平滑キャパシタ(C)から印加される直流電圧をモータ(11a)の駆動電圧に変換する電力変換部(31)と、モータ(11a)の停止時に、上アーム及び下アームのうち一方のスイッチング素子の少なくとも2つをオン状態とし、他方のスイッチング素子をオフ状態とする第1の状態と、上アーム及び下アームのスイッチング素子(S1~S6)をオフ状態とする第2の状態と、を交互に繰り返す制御部(33)と、を備える。
