Tên tiêu đề bằng tiếng anh : Reducing EMI in Buck converter

Reducing Electromagnetic interference (EMI) in switch mode power supplies can be a challenge, because of the very high frequencies that are involved. Electrical components behave differently than expected, because the parasitic effects of the components often play an important role. This application note describes some basics of low voltage buck converter operation with respect to EMI, and provides some practical tips how to reduce EMI in the buck converter design.

When designing a switch-mode converter, electromagnetic compliance is often tested in the later stages of the design phase. If EMI was not considered during the initial stage of the design, it can often be difficult or expensive to reduce EMI afterwards. The best way to ensure a smooth and optimal product design is to consider EMI in the beginning phase of the design. Component choice and layout considerations are crucial in obtaining good EMI performance from the start.
