An insulating sheet includes an adhesive component of a thermosetting resin and containing a filler member. Heat conductivity of an adhesive face region of the insulating sheet is smaller than heat conductivity of an inner region of the insulating sheet.

Insulating sheet and method for producing it, and power module comprising the insulating sheet

A thermally conductive resin sheet includes a thermosetting resin, and a thermally conductive and electrically insulating inorganic filler. The inorganic filler is a mixture of a flat inorganic filler and a granular inorganic filler. The ratio of the volume content, V, of the flat inorganic filler to volume content, V, of the granular inorganic filler in the mixture is from 30/70 to 80/20, in terms of V/V.

Thermally conductive resin sheet and power module using the same

In an inverter system including of an electric-power converter and an ac rotating machine, over-voltage generated in the ac rotating machine is controlled by a low-cost system configuration. The system includes: an electric-power converter; a three-phase ac rotating machine; and a four-core non-coaxial cable, having a ground line and three-phase electric-power supplying lines, connecting the electric-power converter to the three-phase ac rotating machine. One or two capacitors are connected between the ground line and one or two of the electric-power supplying lines, at electric-power supplying terminals on the rotating machine, so that respective capacitances between the three-phase electric-power supplying lines and the ground line are approximately equal to each other.
