Abstract
To enhance the grid integration performance of renewable energy systems,this paper proposes an novel high-frequency isolated LCL-type resonant dual-transformer AC/DC converter structure and conducts a detailed analysis.This improved structure achieves higher power factor and transmission efficiency by reducing the number of components.The topology integrates the dual resonant tank structure from the primary side to the secondary side and controls the output power through phase shift.As a result,the converter can be controlled in a simple and stable manner,achieving full-range soft-switching operation.Based on steady-state analysis,this paper proposes a new set of parameter design schemes and carries out prototype experiments.The experimental results demonstrate the feasibility,efficiency,and practicality of the proposed converter improvement.关键词
