Abstract: PROBLEM TO BE SOLVED: To prevent sudden change of current when performing a mode change.SOLUTION: A PI operation unit 26 of a motor controller calculates a proportional by multiplying a current deviation by a proportional gain and an integration term by multiplying an integrated value of the current deviation by an integral gain on the basis of the current deviation that is a difference between a current command of a motor calculated based on an output torque command of the motor 14 and an actual current of the motor actually measured, and then calculates a supply voltage command to the motor based on the proportional and the integration term. A control mode of the motor includes: an overmodulation control mode which obtains a sine wave output limited by a PWM control; and a PWM mode which obtains a sine wave output by the PWM control. If the current deviation is large when shifting from the overmodulation control mode to the PWM control, the proportional gain is decreased.

Abstract: PROBLEM TO BE SOLVED: To inhibit voltage of a DC power source from becoming overvoltage.SOLUTION: During regenerative control of a motor, when battery voltage Vb becomes less than a threshold value Vref 1, a switch is turned on to make a circuit bypassing a reactor of a step-up converter available and an upper arm of the step-up converter is turned on (S120, S130). When the battery voltage Vb becomes the threshold value Vref 1 or more, the switch is turned off to make the circuit bypassing the reactor unavailable and by using system maximum voltage as a voltage command, switching elements of the step-up converter are controlled (S140, S150). Thus, when the battery voltage Vb becomes less than the threshold value Vref 1, the battery can be efficiently charged by regenerative energy, and when the battery voltage Vb is the threshold value Vref 1 or more, loss of the switching elements Tr1, Tr2 is increased to inhibit voltage on the battery side of the step-up converter from becoming overvoltage.
