Abstract

The design of low-cost power supplies is influenced by the regulations on the low-frequency harmonic content in the line. As IEC 1000-3-2 regulations have just been modified, the design procedure of low-cost power supplies should also be modified. According to the new version of the above-mentioned regulations, many power supplies classified as Class D in the past are classified as Class A now. This fact allows a remarkable saving in the size of the reactive elements used to reduce the line harmonics if they have been properly designed. The minimum values of the magnetic elements used in two well-known PFC solutions (one is an S²PFC and the other is a passive filter) have been obtained in this paper for equipment classified in both the new Class A and the new Class D and for any power level between 75 W and 600 W
