EMI DM filter volume minimization for a PFC boost converter including boost inductor variation and MF EMI limits

For the AC-DC conversion in drive systems, Power Factor Correction (PFC) converters are widely used as they can ensure a high power factor. The EMI filters that are needed for meeting grid regulations have a considerable impact on the total converter volume. In this paper, a method to optimize an EMI filter stage of a PFC converter with respect to volume, is investigated. It includes the optimal choice of the boost inductance value, as it has a big impact on both the converter and the EMI filter design. In addition, different damping topologies are investigated and compared with each other. It is shown that in comparison to a boost inductance value so that the boost inductor current ripple is set to 15 % of the input current, an optimal boost inductance value reduces the total volume of EMI filter and boost inductor up to 17 %.
