Title:
MOTOR CONTROL DEVICE AND POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2023010255
Kind Code:
A
Abstract:
To provide a motor control device and a power conversion device that can improve the accuracy of motor control.SOLUTION: A control device performs motor control processing. The control device acquires detected currents Iu, Iv, and Iw as current acquisition values in a motor control processing step S102. In step S104, the control device calculates a d-axis reference command voltage Vdc and a q-axis reference command voltage Vqc according to the detected currents Iu, Iv, and Iw. In step S105, the control device determines whether it is in a zero-cross state. If it is not in the zero-cross state, the control device proceeds to step S106 to update a d-axis command voltage Vd* and a q-axis command voltage Vq* based on the d-axis reference command voltage Vdc and the q-axis reference command voltage Vqc. If it is in the zero-cross state, the control device proceeds to step S107 to hold the d-axis command voltage Vd* and the q-axis command voltage Vq*.SELECTED DRAWING: Figure 8
