AN827 Datasheet, PDF (14/20 Pages) STMicroelectronics – A 500W HIGH POWER FACTOR WITH THE L4981A

AN827 APPLICATION NOTE
EMI/RFI FILTER
The harmonic content measurement was made with the EMI/RFI filter interposed between the AC source and
the demoboard under test, while the efficiency has been calculated without the filter contribution.
