Abstract: A semiconductor device includes: a plurality of control modules that controls a rotating electric machine. Each control module includes at least two sets of arms, each set including high-side and low-side switching elements that provide an inverter. A plurality of arms of each control module are coupled in parallel to each other with respect to a bus bar coupled to one power source. Each control module includes a metal plate on which the high-side and low-side switching elements are mounted, and mediates an electric coupling with the power source. Each metal plate includes a first metal plate on which one set of arms is disposed, a second metal plate on which another set of arms is disposed, and a coupling plate that couples the first and second metal plates.

Abstract: A semiconductor device includes: a plurality of control modules to control a rotating electric machine. The plurality of control modules are circularly arranged around a rotary shaft of the rotating electric machine. Each control module includes at least one switching element supplied with a current from a bus bar coupled to a power source. The at least one switching element in one of the control modules under a structural condition of arrangement has a lower resistance than another switching element.

Abstract: A control system controls a multiphase rotating machine by a 120° energization process and a PWM process. In the 120° energization process, respective ones of switching elements of a high side arm and switching elements of a low side arm of a power conversion circuit are turned on. In the PWM process, the switching elements of the power conversion circuit turn on/off so that two phases that are connected to the switching elements that are in the on-state are alternately rendered conductive to the high potential side input terminal and the low potential side input terminal of the power conversion circuit.
