Super Cores are made by stacking iron-based nanocrystalline alloy ribbons or laminations. The laminations are banded together by an adhesive rated for a continuous operating temperature of 155°C or 180°C. The nanocrystalline alloy itself has a higher continuous operating temperature. These forms offer a unique combination of high saturation induction (1.25 T), high permeability, super lower core-loss and near zero noise.
Super Cores can be used in medium frequency (20 kHz~100KHz) and high power (up to 300 kW) PV inverters. These have core losses lower than those of 3% or 6.5% Si steels.
