摘　　要：MnZn功率铁氧体广泛应用于高频功率电力电子器件。功率损耗是其最重要的电磁性能指标。宽温低损耗的实现不但可以提高磁性元件在满载工况下的电能转换效率,降低能量损失,而且可以降低设备的待机损耗,提高设备工作时的温度稳定性。本文介绍了实现MnZn功率铁氧体宽温低损耗的途径,总结了国内外宽温低损耗MnZn功率铁氧体的生产和研究开发方面的进展,并对其未来的发展进行了展望。MnZn power ferrite is widely used in high frequency power electronic devices.Loss is the most important index of electromagnetic performance.The realization of wide temperature range and low loss can not only improve the electric energy conversion efficiency of magnetic components under full load condition,reduce the energy loss,but also reduce the standby loss of the equipment and improve the temperature stability of the equipment.This paper introduces the way to realize wide temperature range and low loss of MnZn power ferrite,summarizes the progress of production,research and development of wide temperature and low loss MnZn power ferrite at home and abroad,and prospects its future development.
