Abstract

The invention provides a frequency converter aging method and device, a storage medium and a processor, and the aging method comprises the steps: setting virtual aging equipment in advance, wherein the virtual aging equipment comprises a virtual motor; determining a three-phase AC voltage of the frequency converter according to the parameters of the virtual motor, wherein the three-phase AC voltage is an amplitude-adjustable and frequency-adjustable AC voltage; and controlling the frequency converter to input the three-phase alternating-current voltage into the virtual motor to age the frequency converter. By presetting a virtual motor which is a virtual motor, the frequency converter outputs three-phase AC voltage, therefore, drives the virtual motor to work to realize the aging of the frequency converter, the aging of the frequency converter can be realized without accessing an actual motor load, the three-phase alternating-current voltage is the alternating-current voltage with adjustable amplitude and frequency, the requirements of different post-stage aging equipment can be met, the aging steps of the frequency converter are greatly simplified, and the universality is better.

Description

technical field [0001] The present application relates to the field of frequency converters, and in particular, relates to a frequency converter aging method, aging device, storage medium and processor. Background technique [0002] In the prior art, the on-load aging scheme of the frequency converter will use the actual load during aging. Although this implementation method is simple, it has the following disadvantages: the versatility is very poor, because different types of frequency conversion boards are connected to different loads, It will cause cumbersome aging equipment and complicated aging process; the actual load is not easy to control, that is, the aging power of the board under test is uncontrollable and the consistency is poor; traditional aging solutions generally occupy a large space and are prone to failures, affecting aging efficiency. [0003] The above information disclosed in the Background section is only to enhance the understanding of the background ...
