WebMay 15, 2024 · For EMI purposes, we're mainly interested in the rise time, general switched wave shape, and ringing frequency, if any. Figure 2. The switched waveform (SW) between the output inductor of a DC-DC converter and H-field probe couple through mutual inductance (M). Webence (EMI). In a synchronous buck converter, fast-switching field-effect transistors (FETs) can experience significant voltage overshoots and ringing on the switch node. The magnitude of the ringing is a function of the high-side MOSFET’s switching speed and the stray inductances in the layout and FET package. the hollygood gang https://ticoniq.com

WebEMI and RFI are similar and often have the same causes and solutions. RFI is interference or noise that is radiated - essentially, radio waves. EMI includes RFI but also includes non-radiated interference, such as line noise coming in from power or control lines. From here on we will use only EMI, as treatments are basically the same.
