Abstract:
(EN) A power conversion device according to the present invention is provided with: a power conversion main circuit (10) provided with semiconductor switching elements (10A, 10B); gate drive circuits (12A, 12B) which respectively drive the semiconductor switching elements; and one or a plurality of impedance element groups (16) connected between the at least one set of gate drive circuits (12A, 12B). At least one of the gate drive circuits (12A, 12B) is provided with a detection unit (12A4, 12B4) for detecting the voltage of the impedance element group (16). The drive speeds of the semiconductor switching elements (10A, 10B) are changed in accordance with the outputs of the detection units (12A4, 12B4).
(FR) La présente invention concerne un dispositif de conversion de puissance qui comporte : un circuit principal (10) de conversion de puissance comportant des éléments commutateurs semi-conducteurs (10A, 10B) ; des circuits d’attaque de grille (12A, 12B) qui déclenchent respectivement l’attaque des éléments commutateurs semi-conducteurs ; et un groupe ou une pluralité de groupes d’éléments d’impédance (16) connectés entre l’ensemble ou les ensembles de circuits d’attaque de grille (12A, 12B). Au moins un des circuits d’attaque de grille (12A, 12B) comporte une unité de détection (12A4, 12B4) pour la détection de la tension du groupe d’éléments d’impédance (16). Les vitesses d’attaque des éléments commutateurs semi-conducteurs (10A, 10B) sont modifiées en fonction des sorties de l’unité de détection (12A4, 12B4).
(JA) 本発明に係る電力変換装置は、半導体スイッチング素子(10A,10B)を有する電力変換主回路(10)と、半導体スイッチング素子をそれぞれ駆動するゲート駆動回路(12A,12B)と、少なくとも1組のゲート駆動回路(12A,12B)の間に接続される1または複数のインピーダンス素子群(16)と、を備える。少なくとも1個のゲート駆動回路(12A,12B)は、インピーダンス素子群(16)の電圧を検知する検知部(12A4,12B4)を備え、検知部(12A4,12B4)の出力に応じて半導体スイッチング素子(10A,10B)の駆動速度を変化させる。
