Abstract: Each of semiconductor module includes a semiconductor chip, a case surrounding the semiconductor chip, and a main electrode connected to the semiconductor chip and led out to an upper surface of case. A connecting electrode is connected and fixed to the main electrodes of the adjacent semiconductor modules. The connecting electrode is formed only of a metal plate. The rated current, the rated voltage and the circuit configuration can easily be changed by changing the connection using the connecting electrode, thus enabling reduction of the design time and facilitating manufacture management. Only a malfunctioning one of the semiconductor modules may be replaced. There is, therefore, no need to replace the entire device. The connecting electrode is formed of an electrically conductive plate and, therefore, enables reduction of the number of component parts and reduction of the device in size in comparison with the conventional wiring bus bar.
