Frequent manner performed emissions usually are due to parasitic capacitances like All those with the heatsink and transformer together with the board layout, and switching voltage waveform over the swap. For typical-mode sounds, you may need to reconsider how you've grounded the technique to stop capacitive noise coupling in the https://collinncnxh.bluxeblog.com/63404877/new-step-by-step-map-for-difference-between-emi-and-emc-filter
