Title:
INVERTER CONTROLLER
Document Type and Number:
Japanese Patent JP2010088149
Kind Code:
A
Abstract:
To provide an inverter controller capable of suppressing deterioration in controllability of a motor.
The inverter controller maintains AC currents Iu, Iv and Iw from before a predetermined time t1 of a timing when a level of each of voltages Vu-v and Vw-v between two phases outputted from a motor inverter 41 to a motor 39 is switched to after a predetermined time t2 of two times the predetermined time t1, and controls the ON-OFF of each of switching elements 42-47 of the motor inverter 41 so that the voltage of each of phases outputted from the motor inverter 41 to the motor 39 may be a rectangular wave on the basis of the maintained AC current or AC current not maintained and a command value inputted from the outside.
