Abstract

The present application provides an aging method, an aging device, a storage medium and a processor for a frequency converter. The aging method includes: pre-configuring a virtual aging device, the virtual aging device includes a virtual motor; according to the parameters of the virtual motor, determine the frequency converter Three-phase AC voltage, the three-phase AC voltage is an AC voltage with adjustable amplitude and adjustable frequency; control the inverter to input the three-phase AC voltage into the virtual motor to age the inverter, by setting a virtual motor in advance, the virtual motor is For the virtual motor, the frequency converter outputs three-phase AC voltage according to the parameters of the virtual motor, and then drives the virtual motor to work to realize the aging of the frequency converter. The aging of the frequency converter can be realized without connecting to the actual motor load, and the three-phase AC The voltage is an AC voltage with adjustable amplitude and frequency, which can meet the needs of different post-stage aging equipment, greatly simplifies the aging steps of the inverter, and has good versatility.

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 ...
