The present disclosure aims to provide an electric power steering apparatus which is improved in reliability compared to an existing electric power steering apparatus by configuring redundancy for an electronic system therein. An embodiment provides a electric power steering apparatus including: a four-channel torque sensor including two independent dual die ICs; a four-channel steering angle sensor including two independent dual die ICs; a four-channel motor position sensor including two independent dual die ICs; a dual-wound Brushless AC (BLAC) motor including a first winding motor and a second winding motor therein; a first Electronic Control Unit (ECU); a second ECU; and a selector configured to select an ECU that controls steering among the first ECU and the second ECU. The first ECU and the second ECU are supplied with power from separate power supply devices which are separated from each other, the first winding motor of the dual-wound BLAC motor is connected to an inverter of the first ECU, and the second winding motor of the dual-wound BLAC is connected to an inverter of the second ECU.
