This paper discusses a novel method to validate Sustainable Saturation Operation (SSO) of ferrite inductors in switching power supplies design. SSO is achieved when an inductor operates in partial saturation, with ripple current, power losses and temperature rise fulfilling reliability and efficiency requirements. Achieving inductors SSO permits to reduce the size of power supplies. The method presented...
Ferrite inductors operation in partial saturation offers unexplored opportunities in reducing the size of magnetic parts and the power losses in High-Current-Ripple Switching Mode Power Supplies (HCR SMPSs) using SiC and GaN devices. A reliable prediction of the inductor current ripple is required to exploit such opportunities. A new method for ripple analysis of saturated inductors has been recently...
