A foil-winding technology, which reduces losses of inductors at high ripple currents and high power levels, and a freeware program, which optimizes designs using Litz wire, offer designers new tools for reducing winding losses at high frequencies.rnPower electronics are rapidly expanding into new applications as high-power semiconductor devices increase their rated operating current and frequencies to higher and higher levels. As a basic building block of virtually all power electronics equipment, inductors have a unique potential for improvement. That's because inductors are usually the largest, most expensive and volumetrically inefficient items in a power system.
