Abstract

DC link capacitor is the key component of converter and the relative humidity can affect the performance of elements of DC link capacitor

therefore

the air should be controlled during the production.However

the study of production process in this aspect is less

so it is necessary to study the influence of air humidity on the performance of the DC link capacitor element.In this paper

the production procedure of the DC link capacitor is introduced firstly and the control of air humidity and relative humidity during the production process are introduced in particular.Then

electrical performance test of elements at different process different process and different relative humidity is designed.Finally

the performance difference of DC link capacitor element under different relative humidity during the production process is analyzed throughout the test analysis

which provides good guiding significance for humidity control in the production process of DC link capacitor.
