摘要： DC -DC转换器的电场和磁场的极好来源。他们的EMI频谱开始在开关频率和经常超过100MHz的扩展。在印刷电路板（PCB）布局，以尽量减少电容式联轴器和磁性联轴器护理必须行使。电路的寄生电容和寄生电感，必须进行评估，因此，早在设计阶段可适当权衡。

Layout Considerations for Non-Isolated DC-DC Converters
Abstract: DC-DC converters are an excellent source of electric fields and magnetic fields. Their EMI spectrum
begins at the switching frequency and often extends over 100MHz. To minimize capacitive couplings and
magnetic couplings care must be exercised in printed circuit board (PCB) layout. Parasitic capacitance and
parasitic inductance of the circuit must be evaluated so that the proper trade-off can be made earl
