- To avoid the blindness and limitation of trade - off method on the resolving of smps emi , this paper presents a new research method which is based on using the cadence software . this paper has established the pcb trace noise model of smps , extracted its parasitic elements and simulated its emi level . it has also realized the computer aided emc analyse and computer aided optimized pcb layout
为了避免尝试性修改方法对于解决开关电源电磁干扰的盲目性和局限性，本论文借助cadence软件对开关电源pcb进行了印制导线建模分析、提取寄生参数和电磁兼容仿真分析，实现了开关电源pcb的计算机辅助电磁兼容分析和计算机辅助最优布局设计，从而可以在pcb设计阶段就对其潜在的电磁干扰源进行抑制。 - We choose hb qrc convert as the research object . this paper has completely analyzed the circuit work modes , designed an experimental device , analyzed the mam noise source , established the common - mode and different - mode noise current models , extracted the parasitic elements of four pcb layout and simulated each emi level . based on these , it has derived the element which have great effect on pcb emc and has designed the optimized pcb layout
选择一种半桥准谐振变换器作为研究对象，对其工作原理进行了详细的分析，制作了实验样机，分析了它的主要干扰源，建立了它的共模、差模噪声电流等效电路模型，对它的四种不同pcb布局进行了寄生参数提取和电磁兼容仿真，在此基础上分析得到了影响其电磁噪声水平的最重要因素，并设计出了最优的pcb布局。
