Title:
INVERTER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/139295
Kind Code:
A1
Abstract:
The problem of the present invention is to effectively reduce vibration and noise generated from a motor. An inverter 300 uses a plurality of IGBTs 311 that are switching elements to generate an AC current from a DC current supplied from a DC power supply 10 and supplies the generated AC current to a motor 100 to drive the motor 100. This AC current contains fundamental wave current according to the rotational speed of the motor 100 and harmonic current due to the switching operation of the IGBTs 311. A controller 200 controls a second phase so that a first phase and the second phase are not overlapped with each other at a predetermined motor rotational speed, said first phase being the phase of exciting force periodically occurring at the motor 100 due to the fundamental wave current, said second phase being the phase of exciting force periodically occurring at the motor 100 due to the harmonic current.
