摘要
随着5G通信技术的发展和第3代宽禁带半导体广泛的商用,功率电子器件朝着高频化、小型化和高能效化的方向加速发展.MnZn铁氧体作为功率电子器件的核心材料,成为学术界和产业界在高频软磁材料方面研究的焦点.本综述主要介绍近年来MnZn铁氧体在高频化方向上最新的研究进展,包括通过主成分设计、添加剂调控和低温烧结工艺等手段,实现高频、宽温和低损耗等特性,以及高频下MnZn铁氧体损耗的应力敏感性.随着高频损耗发生机制研究的深入,今后5到10年内将会开发出更多的在0.5 MHz以上的高频和更高的磁通密度下表现出更低损耗的MnZn铁氧体新材料,并迅速应用于通信电源等领域.
With the development of 5G communication technology and the widespread commercial use of the third-generation wide bandgap semiconductors,the power electronic devices with higher frequency,miniaturization and higher energy efficiency become popular.MnZn ferrite as a high-frequency soft magnetic materials of power electronic devices has attracted attention recently.This review introduced the latest research progress on high frequency MnZn ferrites,including the realization of characteristics of high frequency,wide temperature and low loss through the main component design,additive regulation and low temperature sintering process.This review also represented the stress sensitivity of power loss in the high frequency MnZn ferrite.Somefurther researches on the mechanism of high frequency power loss could accelerate the development and application of low core loss high-frequency MnZn ferrite in this decade.
