Abstract
To suppress the increase of the cost and dimensions of an intelligent module which incorporates a 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.
