摘要: 本文针对燃料电池车用多相DC-DC变换器进行了分析与设计。首先针对多相双向DC-DC变换器拓扑进行研究，并通过信号流图(SFG)法对其进行了建模分析，针对连续工作状态(CCM)和断续工作状态(DCM)下的系统工作状态进行了研究。采用电压、电流双闭环对系统进行全数字化控制。搭建了150 kW双向DC-DC变换器实验平台并对系统性能进行了实验验证。
Abstract: This article proposes a multi-phase bidirectional DC-DC converter for FCEV. The Signal Flow Graph (SFG) models for CCM and DCM with bidirectional power flow are analyzed. Based on the transfer function, the dual closed-loop controller is designed. Finally a prototype of 150 kVA DC-DC converter is constructed.
