Research of Dual-loop Control Based on Push-Pull Converter

Tingfeng Zhang

Abstract

In order to enhance the push-pull converter's current stability and the system reliability,the full-state variable dual-loop control system with the full-state variable is constructed based on the push-pull converter's small signal mathematical model.The circuit control system's design process is given in the paper simultaneously,and the concrete design process is analyzed through the simulation software.The simulation comparison and experimental resultsindicated: the dual-loop controller enhanced push-pull circuit's output voltage and the system current stability and the dynamic property,at the same time the control system design is proved correctly.
