由于采用模块组建电源系统具有设计周期短、可靠性高、系统升级容易等特点,模块电源的应用越来越广泛。尤其近几年由于数据业务的飞速发展和分布式供电系统的不断推广,模块电源的增幅已经超出了一次电源。功率密度不断提高随着半导体工艺、封装技术和高频软开关的大量使用,模块电源功率密度越来越大,转换效率越来越高,应用也越来越简单。目前的新型转换及封装技
As the use of modules to form a power system with a short design cycle, high reliability, easy system upgrades and other characteristics, the module power supply is more and more widely used. Especially in recent years due to the rapid development of data services and the continuous promotion of distributed power supply system, the increase of module power has exceeded the power supply. Increasing power density With the extensive use of semiconductor technology, packaging technology and high-frequency soft-switching, the module power density is increasing, the conversion efficiency is getting higher and higher, and the application is more and more simple. The current new conversion and packaging technology
