Abstract:
1. A semiconductor module comprising: a plurality of switching elements each constituting an upper arm part or a lower arm part of a bridge circuit; a high-potential conductor being coupled to a high-potential electrode of a power source, the switching element of the upper arm being disposed on the high-potential conductor; a load conductor being coupled to a load, the switching element of the lower arm being disposed on the load conductor; a low-potential conductor being coupled to a low-potential electrode of the power source; a first connecting conductor having one end connected to the switching element of the upper arm disposed on the high-potential conductor and another end connected to the load conductor; and a second connecting conductor having one end connected to the switching element of the lower arm disposed on the load conductor and another end connected to the low-potential conductor, wherein at least one of the first connecting conductor and the second connecting conductor serves as a shunt resistor for detecting a magnitude of an electric current flowing between the one end and the another end of the at least one of the first connecting conductor and the second connecting conductor.
