    • PROBLEM TO BE SOLVED: To enhance the voltage stabilizing effect of the power line of a system which drives an AC motor by a rectangular wave control system via an inverter by this system voltage, by boosting the voltage of a DC power source with a step-up converter and generating system voltage in a power line.

At that time, it stabilizes torque control and input power control by controlling the torque control of the AC motor 14 and the input power control of the MG unit 30 independently. Furthermore, it executes torque ripple zero control to correct the phase of the rectangular wave voltage so that the deviation between first estimated torque obtained from a detected current vector for torque control of the AC motor 14 and the second estimated torque obtained from a motor detected current vector may be almost zero, whereby it prevents uncomfortable torque ripple at transition of input power control of the MG unit 30.

    • PROBLEM TO BE SOLVED: To precisely perform square wave control for switching a square wave voltage for each electric angle of 60° so that the current applied to an AC motor is commutated at each electric angle of 60°. SOLUTION: The electric angle is determined based on a sample electric angle θes provided by digitizing a detection signal θr of a rotational position sensor 12, When performing square wave control for commutating the square wave voltage applied to an AC motor 11 at each electric angle of 60°, a sample electric angle θes is used that is obtained by digitizing the detection signal θr of the rotational position sensor 12 at such a resolution where a value obtained by dividing an electric angle 360° by 3×2 n is taken as a quantized unit LSB[LSB=360/(3×2 n )]. Thus, the electric angle 60° can be an integer multiple of the quantized unit LSB. The electric angle 60° can be precisely determined without being affected by the error of the sample electric angle θes that is obtained by digitizing the detection signal θr of the rotational position sensor 12. So the square wave control is precisely performed for switching the square wave voltage at each electric angle of 60°. COPYRIGHT: (C)2011,JPO&INPIT
