摘要：
The present work reports the development of a Mn-Zn ferrite material suitable for power applications with core losses amounting to 529 and 296 kW.m(-3) at the operating frequency of 100 kHz and a driving flux density of 200 mT at 25 degrees and 100 degrees C respectively. Power loss values below 400 kW.m(-3) in a wide temperature range above 65 degrees C make it the most promising candidate for regular switching power supplies, as well as in the main transformers of DC-DC converters for automotive applications.
