Fear of Magnetics
by Leland Teschler, Executive Editor, @DW_LeeTeschler Does it really take a voodoo practitioner to design a switching power supply? You might think so judging by the “black art” label that’s often applied to this aspect of power electronics. The reputation for witchcraft here comes in large part from the role magnetic materials play in getting […]
