Title:
インバータ制御装置
Document Type and Number:
Japanese Patent JP7052713
Kind Code:
B2
Abstract:
To provide an inverter controller which can improve torque responsiveness when control transits from PWM control to rectangular wave control.SOLUTION: An inverter controller 20 is configured to switch PWM control and rectangular wave control, and comprises a rectangular wave control unit 40 and a PWM control unit 30. The PWM control unit 30 has: a voltage vector absolute value calculation unit 33 which calculates an absolute value Vdq of a voltage vector Bv on the basis of a table in which a preliminarily stored torque command value Tref is associated with the absolute value Vdq of the voltage vector Bv; a PI control unit 34 which calculates a torque difference value ΔT, an angle θ to be formed by the voltage vector and a q-axis; a command value calculation unit 35 which calculates a d-axis voltage command value Vd* and a q-axis voltage command value Vq* by the absolute value Vdq of the voltage vector Bv and the angle θ; a voltage command value determination unit 36 which calculates three-phase voltage command values Vu, Vv and Vw; and a PWM control signal generation unit 37 which generates a PWM control signal S1.SELECTED DRAWING: Figure 1
