| 摘 要： | 在新能源联合供电系统中,多输入直流变换器(multi-input DC/DC converter,MIC)可实现多路源同时或单独向负载提供能量,从而简化系统结构、降低总体成本、实现能量的优化利用。在需要隔离的应用场合,现有的MIC结构复杂、变压器绕组数量较多。为此该文提出一族不对称型双输入直流变换器,同现有隔离型双输入变换器相比,其优点是结构简单、且可以实现软开关,具有高功率密度和高效率。详细阐述该类变换器的推导过程及其控制策略,以其中某变换器为例,分析其工作原理,并通过一台240 W的原理样机进行实验验证。

| Abstract: | In the hybrid renewable power system,multiple-input DC/DC converters(MICs) serve as the interface of several sources with a load,and provide the load with the energy simultaneously or individually,which can simplify the system configuration and reduce the overall cost.In the applications with isolated requirement,the available MICs usually have a complex configuration and numerous transformer windings.A family of asymmetrical double-input DC/DC converters(DICs) was proposed.Compared with the available isolated DICs,the proposed converters have the advantages of simple architecture and soft-switching realization.The derivation and the control strategy of the converters were illustrated,and the operation principles were analyzed.Finally,the theoretical analysis was validated by the experimental results from a 240 W prototype. |
