A newly developed version of the power module (old version) features lower inductance in the heavy current wiring and better heat dissipation from the power semiconductors so that they can operate at maximum performance. The lower inductance was achieved by a circuit layout that induces eddy currents in the cooling fins on both side surfaces of the power semiconductors and by running multiple wires next to each other to cancel out their surrounding magnetic flux. Similarly, high heat dissipation was achieved by reducing the thermal resistance of the internal insulation layer.
The MCV is a valve for switching cooling water channels that Hitachi Automotive Systems has developed to improve fuel efficiency.
