Title:
INVERTER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057368
Kind Code:
A1
Abstract:
The purpose of the present invention is to readily reduce any voltage error that is caused by dead time, in order to suppress torque shock. This inverter control device 100 controls, through pulse width modulation, a switching operation of an inverter 10 that converts a DC voltage to an AC voltage and applies the AC voltage to a motor 3. The inverter control device 100 according to an embodiment 1 comprises a dead time compensation unit 183 that performs dead time compensation to compensate for an error in the output voltage of the inverter 10, the error being caused by dead time of the inverter 10. The dead time compensation unit 183 performs dead time compensation on the basis of a difference θvi between an electric current phase angle θi indicating a phase angle for outputting the electric current of the motor 3, and a voltage phase angle θv for outputting a voltage that corresponds to the electric current.
