摘要
文中建立了主从均流控制下的并联Buck变换器的数学模型。从动态特性上来说,保留了主变换器的原有设计特性,从变换器强制改变原有的特性,跟随主变换器电流。同时还研究了基于UC3842模块下的主从控制均流现象,并分析两者的特性。
The mathematical model of master-slave control in parallel-buck converter is presented in this paper.In terms of dynamic characteristics,the main converter keeps the original characteristic ; the slave converter changes the characteristic and follows the current of main converter.At the same time,It shows current sharing phenomenon in parallel-buck converter in master-slave control mode based on UC3842.
