摘要： According to a power semiconductor device of the present invention, it comprises a plurality of lead frames formed into like a wiring pattern, a power semiconductor element joined onto the lead frame, and a capacitor placed between mutually adjacent two lead frames, and is encapsulated with a mold resin. The capacitor is characterized in that external electrodes of that capacitor are connected to the lead frames each through a stress-relaxation structure portion that is lower in rigidity than the capacitor.

摘要： To obtain a rotating electrical machine preventing a functional failure and shortening of the life of brushes caused by a temperature rise of the brushes installed to a vehicle AC power generator or a motor generator. A brush holder holding brushes supplying a field current to a rotor is provided with brush temperature suppressing metal members installed substantially parallel to the brushes in the vicinity of abutment portions of the brushes and slip rings in point-, line-, or surface-contact with the brushes at least at one point besides energization terminals. The brush temperature suppressing metal members not only diffuse heat generated at the brushes, but also function as a heat capacity for a case where a large amount of heat is generated in a short time, such as during regenerative power generation and a start-up operation, and thereby prevent an excessive temperature rise of the brushes.

摘要： An electric rotating machine is provided that efficiently radiates heat, caused in the vicinity of a portion where a brush and a slip ring makes contact with each other, to the outside of a brush holder and that can prevent the temperature of the brush from excessively rising. The brush holder holding the brush that supplies a magnetic-field current to a magnetic-field winding by way of the slip ring is provided with an energization terminal that electrically connects a magnetic-field circuit with the brush and a brush cooling metal member that cools the brush; the brush cooling metal member radiates heat, generated in the vicinity of a contact portion between the brush and the slip ring, to the outside of the brush holder.
