Title:
CONTROL APPARATUS OF THREE-PHASE ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2016163452
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a control apparatus of a three-phase rotary electric machine, capable of properly suppressing the reduction of a setting accuracy of a time ratio due to a dead time.SOLUTION: Different values from each other are set to a time ratio of D(1), D(2), and D(3) in a plurality of periods TD having plural times (for example, three times) of a length of a period Tc of a carrier are set. An average value of the time ratio of D(1), D(2), and D(3) is set to a demand time ratio (for example, 89%) as an operation amount for controlling a control amount of a three-phase rotary electric machine to a command value. In this time, a value of the time ratio of D(1), D(2), and D(3) can be set in high accuracy without receiving an influence of a dead time provided at complementary on/off operating a switching element on an upper side arm and a lower side arm.SELECTED DRAWING: Figure 5
