Abstract
Provided is an electric power steering device including a motor-including a first and a second three-phase windings, first and second inverter circuits configured to supply electric power to the first and second three-phase windings, respectively, a boost circuit configured to change a voltage of electric power to be supplied to each of the first and second inverter circuits, and a drive unit configured to cause, when an abnormality occurs in any one of a first system including the first three-phase winding and the first inverter circuit and a second system including the second three-phase winding and the second inverter circuit, to supply electric power at a higher voltage than a voltage before the occurrence of the abnormality to an inverter circuit included in a normal system by the boost circuit, the normal system being one of the first system and the second system, to thereby drive the inverter circuit.
