An EMI filter must be sufficiently damped in order to avoid undesirable interactions with the converter input impedance or source output impedance, which otherwise may lead to instability and degraded control performance. Optimal damping of …
WebThe first method is to design a wide-band EMI filter at the high-voltage input port of the DC-DC converter. It can achieve the insertion loss of 60dB within 150kHz-108MHz. Another proposed method is to design a PCB-level EMI filter based on …
WebA poorly damped filter can also have significant effects on the stability of a power converter. The damping of the filter is directly related to the output impedance of the EMI filter. A typical approach for damping the filter is to use a parallel RC circuit (the damping network shown in Figure 2). This replicates the electrical characteristics of imatter domestic abuseWebModified buck converter with an output LC filter. While the original filter stage may not have had problems with instability in its design, adding the new filter stage can produce new poles, which would be apparent in the combined filter’s transfer function.
