Title (EN) TRANSISTOR DRIVE CIRCUIT AND MOTOR DRIVE CONTROL DEVICE
(FR) CIRCUIT D'ATTAQUE DE TRANSISTOR ET DISPOSITIF DE COMMANDE D'ENTRAÎNEMENT DE MOTEUR
(JA) トランジスタ駆動回路及びモータ駆動制御装置
Abstract: front page image
(EN)According to this transistor drive circuit, the temperature of a bipolar transistor (1) or a MOSFET (2) is detected by a temperature detection element (15), and if the temperature is no more than a threshold, both the MOSFET (2) and the bipolar transistor (1) are turned ON, and if the temperature exceeds the threshold, then only the bipolar transistor (1) is turned ON.
(FR)Selon ce circuit d'attaque de transistor, la température d'un transistor bipolaire (1) ou d'un MOSFET (2) est détectée par un élément de détection de température (15), et si la température n'est pas supérieure à un seuil, à la fois le MOSFET (2) et le transistor bipolaire (1) sont activés, et si la température dépasse le seuil, alors seul le transistor bipolaire (1) est activé.
(JA)本開示のトランジスタ駆動回路によれば、バイポーラ型トランジスタ(1)又はMOSFET(2)の温度を温度検出素子(15)により検出し、その温度が閾値以下であればMOSFET(2)とバイポーラ型トランジスタ(1)との双方をオンさせ、前記温度が閾値を超えるとバイポーラ型トランジスタ(1)のみをオンさせる。
