摘要
介绍一种高品质变频电源。其整流器采用APFC技术 ,逆变器采用无相差频率跟踪技术 ,使输入和输出的功率因数都得以提高 ,这对电网。
The high quality frequency conversion power supply is introduced in this paper. it can raise the input and ouput power factor. because of bridge rectifier adopting APFC technology and inverter adopting the frequency tracing technoiogy of no phase difference, which have very important significance on effective running of power network? frequency conversion power supply and loading.
