Electromagnetic interference (EMI) filter is an integral part of most switching power converter design. 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 single-stage LC filters that achieves maximal damping effects with minimal damping component size and power loss has been reported. Multistage EMI filters… CONTINUE READING
