First Claim
1. A semiconductor device comprising:
- a plurality of power elements that configures an inverter;
a conductive plate that electrically connects the plurality of power elements; and
a current detection portion that detects a current of the plurality of power elements based on a magnetic field generated by a flow of a current input to the plurality of power elements and a current output from the plurality of power elements,wherein;
the plurality of power elements at least include a first power element and a second power element;
the conductive plate includes;
a first carrying portion to which a first end of the first power element is connected;
a second carrying portion to which a first end of the second power element is connected;
a third carrying portion to which a second end of the first power element is connected;
a fourth carrying portion to which a second end of the second power element is connected;
first connection portion that electrically connects the second carrying portion and the third carrying portion to connect the first power element and the second power element in series; and
an output terminal electrically connected with the second carrying portion or the third carrying portion;
the first carrying portion is connected with a first power source and the fourth carrying portion is connected with a second power source; and
the current detection portion is fixed to the output terminal and the magnetic field generated by the flow of the current of the output terminal permeates the current detection portion.

Abstract
A semiconductor device includes: power elements that configures an inverter; a conductive plate that electrically connects the power elements; and a current detection portion. The power elements include a first power element and a second power element. The conductive plate includes: a first carrying portion; a second carrying portion; a third carrying portion; a fourth carrying portion; a first connection portion that electrically connects the second carrying portion and the third carrying portion to connect the first power element and the second power element in series; and an output terminal electrically connected with the second carrying portion or the third carrying portion. The first carrying portion is connected with a first power source and the fourth carrying portion is connected with a second power source. The current detection portion is fixed to the output terminal and the magnetic field permeates the current detection portion.
