Abstract

A power module includes a double-sided electrode module, a power semiconductor element, a pair of base plates, and a connecting member. The double-sided electrode module has a plurality of electrode wiring boards and a power semiconductor element which are molded with a resin material. The pair of base plates has the double-sided electrode module sandwiched therebetween. The pair of base plates are connected via the connecting member. The connecting member is formed in a curved shape.

Claims (18)

1. A power module, comprising:

a double-sided electrode module having a plurality of electrode wiring boards and a power semiconductor element which are molded with a resin material;

a pair of base plates between which the double-sided electrode module is sandwiched; and

a connecting member via which the pair of base plates are connected, wherein the connecting member is formed in a curved shape, the curved shape being devoid of any openings, wherein

a thickness of the connecting member is less than a thickness of each of the base plates,

the pair of base plates and the connecting member are formed as a single piece,

each of the pair of base plates has a plurality of outer edges, and

the connecting member is connected to the plurality of outer edges of each of the pair of base plates.

2. A power module, comprising:

a double-sided electrode module having a plurality of electrode wiring boards and a power semiconductor element which are molded with a resin material;

a pair of base plates between which the double-sided electrode module is sandwiched; and

a connecting member via which the pair of base plates are connected, wherein the connecting member has a bent portion, wherein

a thickness of the connecting member is less than a thickness of each of the base plates,

the pair of base plates and the connecting member are formed as a single piece,

each of the pair of base plates has a plurality of outer edges, and

the connecting member is connected to the plurality of outer edges of each of the pair of base plates.

3. The power module according to claim 2 , wherein

the bent portion is bent toward the double-sided electrode module.
