基于ANSYS的等离子体破裂防护快阀电磁力分析

The Analysis of Eddy Current Electromagnetic Force Based on ANSYS

依据电磁感应原理,变化磁场周围的导体会受到电磁力的作用,依靠该效应的涡流驱动快速充气阀已经在中科院等离子体所研制成功。利用ANSYS有限元分析软件,计算不同脉冲电流、不同线圈电感及线圈与阀芯不同间距情况下导体所受电磁力。找到影响电磁力的主要因素,为快阀的改进提供理论依据。

Current loop and voltage loop digital controller design of DCM Boost PFC are discussed in this pa- per, simulation and experiment test verified the feasibility of the controller. As the controllers are based on DSP, it is convenient to adjust controller parameters according to the result of experiment test, thus keep a balance between loop stability and THD.
