摘要

摘要: 为满足等离子体放电需求，垂直场电源需串联脉冲电感来改变输出电流参数。针对TT-1装置垂直场电源对输出电流的要求，对脉冲电感进行了设计与研制。根据电感的运行工况及参数，通过感应系数法和累积温升法进行详细的数学分析和结构设计。基于理论设计，建立Ansys仿真模型对电感进行了磁场及温升的研究。最后完成电感的研制，根据电桥测量和实验波形，实际电感参数与理论分析高度吻合，并对电感进行大电流条件下的疲劳实验和温升实验，验证理论设计的可靠性。

Abstract: To meet the demand of plasma discharge, pulse inductor should be connected to the vertical field power supply to change the output current parameters. To satisfy the need of the output current of the vertical field power supply of the TT-1 device, pulse inductor was designed and developed. According to the operating conditions and parameters of the inductor, the detailed mathematical analysis and structural design were carried out by the induction coefficient method and cumulative temperature rise method. Based on the theoretical design, an Ansys simulation model was established to study the magnetic field and temperature rise of the inductor. Finally, the inductor was developed. According to the bridge measurement and experimental waveform, the actual inductance parameters agree well with the theoretical analysis. The experiment of fatigue and temperature was carried out on the inductor under the condition of high current to verify the reliability of the theoretical design.
