摘要
在电子产品的设计和制作中,为了提高效率并降低成本,通过仿真电子器件来预估电磁特性变得越来越重要。利用ANSYS SIwave对PCB的耦合和谐振进行仿真分析,并根据仿真效果对PCB增加去耦电容。通过电压检测探针进行测试,测试结果表明该仿真优化可以大幅减少实际系统阻抗匹配设计的盲目性,有效提高系统传输效率。
In the design and production of electronic products,in order to improve efficiency and reduce costs,the process of electromagnetic characteristics estimation through the simulation of electronic devices is becoming more and more important.In this paper,the coupling phenomenon and resonance of PCB are simulated by using ANSYS Siwave.According to the simulation results,the coupling capacitance of PCB is increased and the voltage detection probe is simulated.The test results show that according to the conclusions in this paper,the blindness of impedance matching design of the actual system can be greatly reduced,and the power transmission capacity and overall efficiency of the system can be effectively improved.
