Abstract
An electronic apparatus includes a rotating electric machine that has a plurality of multi-phase winding sets, each of which has a plurality of phase windings; a plurality of inverter circuits that are connected to the plurality of multi-phase winding sets respectively; and a control circuit that controls the plurality of inverter circuits such that a multi-phase alternating current is supplied to each of the plurality of multi-phase winding sets from each of the plurality of inverter circuits. The control circuit determines that a short circuit occurs when i) a plurality of phase current added values obtained by adding each phase current flowing through each of the plurality of phase windings calculated at each of the plurality of multi-phase winding sets; and ii) an absolute value of a total phase current added value obtained by adding all of the plurality of phase current added values is smaller than a predetermined value.
