Title:
INVERTER CONTROLLER
Document Type and Number:
Japanese Patent JP2015173549
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inverter controller capable of high-efficiently controlling an inverter motor while stabilizing the torque in a high-speed range of the motor without increasing the computation amount of a microcomputer.SOLUTION: When the rotation speed of a motor exceeds a predetermined value, a three-phase voltage command for an inverter is generated on the basis of the angle and is binarized using a maximum voltage and a minimum voltage that the inverter can output. The generated three-phase voltage command and a reference value are compared to each other to generate a switching pulse for the inverter.
