http://www.ipcalculus.com info@ipcalculus.com Over view 2011 © IPCalculus Services Historically, the capabilities and size of transformer units were limited by the frequency that the switching transistors were able to operate at, 20kHZ being the best one could expect. However, MOSFETs smashed this barrier apart, offering switching frequencies in excess of 250kHZ. Thus the limiting step of low switching frequencies had been removed from transformer design. This in turn was now replaced by the next limiting step: namely the physical design of the traditional ‘wire-wound’ transformer itself . It is Planar transformers that overcome this new limiting step, resolving many of the problems of traditional wire-wound transformers and provide significant reductions in the size and weight, improved efficiencies and much simpler manufacturing methods. The name planar implies that the geometry of these transformers is more of a two-dimensional component, rather than the traditional three-dimensional wire-wound equivalents. Planar technology comprises two major design features that distinguish it from the old-fashioned ‘wire-wound’ transformers: 1. The windings are replaced by flat copper foil lead frames and can even be embedded into a printed circuit board 2. These flat windings are then mounted between thin, very lightweight, ferrite cores
