An RFI filter is required for best performance when connecting the preconverter directly to the ac line. The filter attenuates
the level of high frequency switching that appears on the ac line current waveform. Figures 20 and 21 work well with
commercially available two stage filters such as the Delta Electronics 03DPCG5. Shown above is a single stage test filter
that can easily be constructed with four ac line rated capacitors and a commonmode transformer. Coilcraft CMT3282
was used to test Figures 20 and 21. It has a minimum inductance of 28 mH and a maximum current rating of 2.0 A. Coilcraft
CMT4179 was used to test Figure 22. It has a minimum inductance of 17 mH and a maximum current rating of 9.0 A. Circuit
conversion efficiency h (%) was calculated without the power loss of the RFI filter.
