Embodiment Construction

[0019] Embodiments of a switching element unit and a switching element module will be described with reference to the drawings. In addition, terms related to dimensions, arrangement directions, arrangement positions, etc. of each component in the following description are concepts that include states that have differences due to errors (errors of an acceptable level in manufacturing). In addition, in this specification, a "rotating electric machine" is used as a concept including a motor (electric motor), a generator (generator), and any one of the motor and the generator functioning as both the motor and the generator as necessary.

[0020] The switching element unit 10 is used in an inverter circuit 100 for power conversion between DC power and AC power (refer to Figure 7 ). Such as Figure 7 As shown, the inverter circuit 100 is provided between the DC power supply 6 (supply source of DC voltage) and the rotary electric machine MG. The DC power supply 6 is configured us...

Abstract

The present invention relates to a switching element unit and a switching element module. In the present invention, a first switching element (31) and a second switching element (32) are disposed so as to be arrayed in a first direction (X). An output busbar (40) is disposed along the first direction (X). The first switching element (31) and the second switching element (32) are disposed so as tobe embedded in a molded part (2). The output busbar (40) comprises: an embedded section (40c) that is embedded in the molded part (2); a first exposed section (40a) that is exposed from the molded part (2) on one side in the first direction (X) in relation to a switching element group (20); and a second exposed section (40b) that is exposed from the molded part (2) on another side in the first direction (X) in relation to the switching element group (20).

Description

technical field [0001] The present invention relates to a switching element unit including a switching element group constituting an inverter circuit, and a switching element module including a plurality of such switching element units. Background technique [0002] An example of such a switching element unit is described in JP-A-2002-369496 (Patent Document 1). Patent Document 1 discloses a process for preventing errors caused by unbalanced switching of power elements when intelligent power modules (IPMs) constituting an inverter circuit are connected in parallel and used. Current detection, heat concentration technology. Although it is not clearly described in Patent Document 1, by connecting the IPMs in parallel in this manner, the current capacity of the inverter circuit as a whole can be increased to drive large-capacity AC equipment. [0003] However, in the case of a structure in which the current capacity of the entire switching element module including a plurality...
