一,前言 随着集成电路、大规模集成电路和超大规模集成电路等半导体技术的迅速发展,各种电子设备和装置已进入了小型化、高功能化的阶段,对电源也进一步提出小型、轻量、高功率、高性能和高可靠性的要求。 电源小型化的主要技术途径就是实现集成化、高频化,而高频化的关键除了解决大功率高速开关管和快速恢复整流管外,主要是解决高频、高磁感下的低损耗变压器铁芯问题。高频综合性能优异的钴基非晶合金就成为铁芯用材料的重点研究对象。
I. INTRODUCTION With the rapid development of semiconductor technologies such as integrated circuits, large-scale integrated circuits and very large-scale integrated circuits, a variety of electronic devices and devices have entered the stage of miniaturization and high-functionalization. The power supply is further proposed as small and light Volume, high power, high performance and high reliability requirements. Power miniaturization is the main technical way to achieve integration, high frequency, and the key to high frequency In addition to solve the high-power high-speed switch and fast recovery rectifier, the main is to solve the high-frequency, high magnetic induction of low loss transformer Iron core problem. High-frequency synthesis of cobalt-based amorphous alloy has become the core material of the key research object.
