近来，已经开发了用于高效率和高功率密度电动机的新型磁性材料。此外，下一代半导体器件，如碳化硅（SiC）或氮化镓（GaN），由于其高频操作，已被引入用于功率转换器。因此，新磁性材料在GaN或SiC逆变器驱动下的高频操作是可能的。然而，当磁性材料被高频信号激励时，其铁损特性尚未进行。本文介绍了在高载波频率激励下使用GANFET逆变器的磁性材料的铁损特性。通过在不同空载时间下在5至500 kHz的载波频率下对铁损进行实验评估来进行这种表征。作为测量的结果，铁损似乎在高载波频率和大空载时间下有增加的趋势。此外，还介绍了滤波技术，它似乎是一种有效的减少铁损的技术。
Recently, novel magnetic materials have been developed for high-efficiency and high power density electric motors. In addition, next-generation semiconductor devices, like silicon carbide (SiC) or gallium nitride (GaN), have been introduced for power converters due to their high-frequency operation. Therefore, high-frequency operation of new magnetic materials is possible when they are driven by GaN or SiC inverters. Nevertheless, iron loss characterization of magnetic materials when they are excited by high-frequency signals have not been conducted yet. This paper introduces the iron losses characterization of a magnetic material at high carrier frequency excitation using a GANFET inverter. This characterization was carried out by the experimental evaluation of iron losses at carrier frequencies from 5 to 500 kHz at different deadtimes. As a result of the measurements, iron losses seem to have a trend to increase at high carrier frequencies and large deadtimes. In addition, filtering is introduced and it seems to be an effective technique for reducing iron losses.
