摘要： A microcomputer calculates a command value for feedback control based on a target electric current value set on the basis of steering torque and a vehicle speed, and the detecting value of a motor electric current. The microcomputer calculates the duty ratio of a PWM signal for turning on and off a switching element of a motor driving circuit from this command value. When this calculated duty ratio is 100% or less, no voltage raising circuit is operated and a battery voltage is supplied to the motor driving circuit. In contrast to this, when the calculated duty ratio Dc exceeds 100%, the microcomputer outputs the PWM signal for turning on and off the switching element of the voltage raising circuit in the duty ratio according to this excess amount. Thus, the battery voltage is raised in accordance with this excess amount and is supplied to the motor driving circuit.

摘要： A motor driver includes an inverter having at least one arm including two series-connected switching elements and converting a direct current to an alternating current to supply the alternating current to an electric motor, a booster circuit connected between the inverter and a DC power supply and including a reactor, a switching element and a reverse-flow preventing diode, the booster circuit supplying the direct current from the DC power supply to the inverter, a current detector for detecting current flowing into the booster circuit, a speed detector for detecting a rotational speed of the motor, and a controller for comparing a speed value detected by the speed detector with a set speed value, thereby determining a command value. The controller controls the inverter on the basis of the command value by pulse width modulation and further controls the booster circuit pulse width modulation so that the booster circuit executes a voltage boosting operation and the current detector so that the detected current value does not exceed an upper limit value.
