To suppress the increase of the cost and dimensions of an intelligent module which incorporates the control function with the driving circuit device having a bridge circuit for driving inverters etc. The module (70) has a rectangular base plate (30), along the long side of which are aligned power semiconductor elements (10). Chips of control input circuits (20) are displaced along the short side of the base plate (30), and arranged in close proximity to the corresponding semiconductor elements. Input terminals (P, N) and output terminals (U, V, W) are arranged on the long side of the base plate (30) along which the semiconductor elements (10) are arranged. Control input terminals (Tc) are arranged on another long side of the base plate (30). The input and output terminals are connected via conductors (40) with the corresponding semiconductor elements (10). And, the control input terminals (Tc) are connected via a wiring board (50) with the corresponding control input circuits (20). <MATH> |
