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 16 and 17 work well with commercially available two stage filters
such as the Delta Electronics 03DPCG6. Shown above is a single stage test filter that can easily be constructed with four ac line rated
capacitors and a common--mode transformer. Coilcraft CMT3--28--2 was used to test Figures 16 and 17. It has a minimum inductance of 28 mH
and a maximum current rating of 2.0 A. Coilcraft CMT4--17--9 was used to test Figure 20. It has a minimum inductance of 17 mH and a
maximum current rating of 9.0 A. Circuit conversion efficiency  (%) was calculated without the power loss of the RFI filter.
