交流感应电机驱动系统电磁兼容设计
资料介绍
交流感应电机驱动系统属于强电零部件,大功率电力电子系统工作时,将发出强烈的电磁干扰,影响附近其它的车载设备正常工作,甚至对行车安全造成威胁.因此有必要对驱动系统的EMC设计进行研究.本文主要目的就是从布局和缓冲电路两方面进行电磁干扰的分析研究,提出在硬件电路和机械结构层面的优化设计,包括电场磁场的屏蔽、车辆接地和在IGBT开关电路上增加缓冲电路等电磁干扰抑制措施,并进行了仿真分析验证其有效性.
The drive system of AC induction motor belongs to the heavy electric components. The high - power electronic devices will produce strong EMI during their operations, which may influence the normal work of other electrical equipment, even endanger vehicle safety. Therefore, it is necessary to study the EMC design of fuel cell vehicle. This paper aims atconducting the analysis of EM! from the layout and buffer circuit, and will bring out the optimization design for the hardware circuits and mechanical structures, including shielding of elec- tromagnetic fields, grounding and adding buffer circuit in IGBT circuit. Simulation analysis verifies the effective EMIsuppression measures.
