Abstract :
In switching power converter circuits, EM noise can couple between PCB traces through the effect of electric field coupling. An experiment using a flyback power converter verifies the severity of this effect. Further experiments and field plots confirm that a good PCB layout can significantly reduce conducted EMI due to unintentional E-field coupling
