摘要：
A DC distribution system architecture based on AFEC(Active Front-End Controller) is proposed to effectively employ and manage the renewable energy resources at customer side, which adopts the AFEC designed based on power electronics technique and high-frequency isolation technique to integrate the distribution step-down transformer with the AC-DC converter for the power conversion between medium-voltage AC grid and low-voltage DC grid. The basic types and different practical applications of AFEC are introduced. The system topology of cascaded AFECs with series inputs and parallel outputs, as well as the functions of its different modules, are analyzed in detail. A small experimental system based on the cascaded AFECs integrating dual Boost/Buck full-bridge converter with CLLC resonance module is built to verify the feasibility of the overall system architecture and the validity of its control strategy. © 2016, Electric Power Automation Equipment Press.
