N2 - At present, Y capacitor is widely adopted inside an isolated switched mode power supply to pass EMI tests. However, to meet certain safety standard, engineers are trying to reduce the Y-cap in such equipment as cell phone and pad chargers, medical instruments, handheld and portable equipment. As we know, the removal of Y-cap offers a big challenge for the EMI design. To solve the problem, this paper proposed an optimized transformer design method. By means of this method, the EMI noise can be reduced without the need of the traditional Y-cap. Analysis of the transformer architecture as well as the auxiliary winding has been carried out. The experiment results demonstrated the effectiveness and feasibility of the proposed method.
