Title:
CONTROLLER OF DYNAMO-ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2015046956
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a controller of dynamo-electric machine capable of avoiding decrease of reliability of a motor generator and an inverter suitably.SOLUTION: A phase calculation unit 30i calculates a FB voltage phase δfb for feedback controlling the torque of a motor generator to a command torque Trq*. An operation signal generation unit 30l generates operation signals gU#, gV#, gW# for on/off operation of switching elements constituting an inverter based on the FB voltage phase δfb. When a current amplitude In calculated by a current amplitude calculation unit 30j exceeds a predetermined value, a voltage phase limitation unit 30k performs limitation processing of the FB voltage phase δfb.
