    • An electric power steering apparatus includes a booster circuit and a microcomputer. The booster circuit includes a booster coil, a first FET, and a second FET. The booster coil is connected to the first FET, which is grounded. A node a between the booster coil and the first FET is connected to the second FET, which is connected to a drive circuit. The microcomputer drives the first and second FETs such that the first and second FETs are selectively turned on and off, thereby controlling an output voltage of the booster circuit. When application of assisting force to a steering system is stopped, the microcomputer holds the second FETs on until the output voltage of the booster circuit becomes equal to a predetermined voltage.

    • A motor control device is provided, wherein an electric power (P) consumed by the brushless DC motor is inferred from three parameters including motor phase currents (I) flowing through at least two phases of three phases of the brushless DC motor, motor phase voltages (V) applied to at least two phases which of the three phases, are the same in phase as the motor phase currents (I) flowing through the two phases, and a motor rotational angle (θ). Then, the value of a power supply current (Ib) supplied to the three-phase inverter is inferred based on the electric power (P) inferred to be consumed by the brushless DC motor and the power supply voltage (Vb) applied to a three-phase inverter. In accordance a flow chart shown in FIG. 3, the consumed electric power (P) is inferred by an expression (1) at step 337, the power supply current (Ib) is inferred by an expression (2) at step 338, and the inferred power supply current (Ib) is output to make it possible to detect the overcurrent supplied to the three-phase inverter.
