摘要
提出一种隔离型三端口双向DC/DC变换器,设计了其主要工作模式的控制策略,并通过增加辅助电容在该模式下各输出端口之间实现功率解耦,提升系统稳定性和动态性能,最后搭建一台3.3 kW的试验样机,对理论分析和设计进行验证。
An isolated three-port DC/DC converter was proposed.The control strategy of the main working mode was also designed.Decoupling power between output ports in this mode by adding auxiliary capacitors,the system stability and dynamic performance were improved.Finally,experiment was done on a 3.3 kW prototype to verify the validity of the proposed theoretical analysis and design.
