Abstract
(EN) This half-bridge circuit passes electric current from a second terminal to a third terminal or from the third terminal to the second terminal according to the polarity of the voltage between the second terminal and the third terminal when the voltage between the first terminal and the third terminal, or the voltage between the first terminal and the second terminal, is at or above a threshold voltage. When electric current is passed from the third terminal to the second terminal, the voltage between the second terminal and the third terminal varies in relation to the applied voltage between the first terminal and the third terminal, within a range in which the voltage between the first terminal and the third terminal is equal to or less than the threshold voltage. The applied voltage for turning off a switch element is set by switching between substantially zero voltage between the first terminal and the third terminal and a negative bias voltage. The voltage applied between the first terminal and the third terminal in order to turn off the first switch element is switched to substantially zero voltage before turning off a second switch element.
(FR) Cette invention concerne un circuit en demi-pont transmettant un courant électrique d'une deuxième borne à une troisième borne ou de la troisième borne à la deuxième borne en fonction de la polarité de la tension entre la deuxième borne et la troisième borne quand la tension entre la première borne et la troisième borne ou la tension entre la première borne et la deuxième borne est supérieure ou égale à une tension seuil. Quand le courant électrique est transmis de la troisième borne à la deuxième borne, la tension entre la deuxième borne et la troisième borne varie par rapport à la tension appliquée entre la première borne et la troisième borne, dans une plage dans laquelle la tension entre la première borne et la troisième borne est inférieure ou égale à la tension seuil. La tension appliquée pour ouvrir un élément de commutation est déterminée par commutation entre une tension sensiblement nulle entre la première borne et la troisième borne et une tension de polarisation négative. La tension appliquée entre la première et la troisième borne pour ouvrir l'élément de commutation est rendue sensiblement nulle avant l'ouverture d'un second élément de commutation.
(JA)  本開示に係るハーフブリッジ回路は、第1の端子と第3の端子との間電圧又は第1の端子と第2の端子との間電圧が閾値電圧以上の時は、第2の端子と第3の端子との間の電圧の極性に応じて第2の端子から第3の端子へ、又は第3の端子から第2の端子へ電流を流す。第3の端子から第2の端子へ電流を流した時に、第1の端子と第3の端子との間の電圧が閾値電圧以下の範囲において第1の端子と第3の端子との間への印加電圧に対して第2の端子と第3の端子との間の電圧が変化する。スイッチ素子をターンオフ制御する印加電圧は、第1の端子と第3の端子との間へ略ゼロ電圧と負バイアス電圧を切り替えて設定する。第1のスイッチ素子をターンオフ制御するための第1の端子と第3の端子との間へ印加する電圧は、第2のスイッチ素子をターンオフ制御する前に、略ゼロ電圧に切り替える。
