In general, the conducted electromagnetic interference (EMI) emission exists in most of the electronic products and affects the electromagnetic environments. In this paper, we design a switching circuit to observe and improve the conducted EMI emission. We also discuss the conducted EMI effects with putting RC snubber or diode into the switching circuit. It is found that the switching circuits with RC snubber or diode can reduce the conducted EMI effect and accord with the limitations of FCC Part 15 Class B and EN 55011 Class B.
