Integrated module including power semiconductor switches with control circuit - has control circuits for power transistor circuit integrated in single module including cooling vanes

摘要

The module includes two power semiconductor devices (2,3) arranged on respective cooling vanes (1), which are electrically connected to the collectors. The cooling vanes form switchable load connections. The emitters of PNP transistors (2) are connected together by a metal strip (5) which forms the pulse connection terminal (6). The emitters of NPN transistors (3) are connected together by a metal strip (7) which forms the negative terminal (d) of the module. A switching and control device (4) is integrated in one of the semiconductor devices in the respective cooling vane, and the control terminal (12) forms the control terminal of the module. The switching and control device of one component is connected via a bridge (10) to the control layer of the semiconductor device of the other component. USE - For electronically commutated EG or DC motors, also for interfaces for computers or digital circuits.
