Abstract
A power conversion apparatus includes: a semiconductor module including a built-in switching element; and a pair of bus bars connected to a power terminal of the semiconductor module. The pair of bus bars has body plate parts that are arranged so as to at least partially face each other in a thickness direction, and pluralities of terminal connection parts that are branched from the body plate parts and to which the power terminal is connected. At least one of the pair of bus bars has a plurality of annular parts that are annularly formed so as to include the plurality of terminal connection parts.
Claims8
A power conversion apparatus comprising:
- a semiconductor module comprising a built-in switching element;
- and
- two bus bars connected to respective power terminals of the semiconductor module, wherein
- the bus bars have (i) body plate parts, which are arranged so as to at least partially face each other in a thickness direction of the body plate parts, and (ii) pluralities of terminal connection parts that are branched from the body plate parts and to which the power terminals are connected,
- one of the bus bars has a plurality of annular parts that are annularly formed so as to include the plurality of terminal connection parts of the one bus bar,
- the plurality of annular parts are linearly arranged in a direction orthogonal to the thickness direction, and
- the one bus bar has an edge bent part that is bent in the thickness direction at an edge of the one bus bar that extends along an arrangement direction of the plurality of annular parts.
