Title:
INVERTER CONTROL METHOD AND INVERTER CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/225016
Kind Code:
A1
Abstract:
Provided is an inverter control method for performing a general switching control for switching an inverter in response to a request of a motor, in an inverter control system provided with the inverter which regulates electric power supplied to the motor, the method comprising: an estimation step for estimating, on the basis of a motor state parameter which represents the state of the motor, a rise in an inverter voltage, which is a direct current voltage of the inverter when the general switching control is stopped, while the general switching control is being performed; and a determination step for determining, on the basis of the estimation result of the rise in the inverter voltage, whether the general switching control is stopped.
