摘要
双向DC/DC变换器在新能源和多端口系统中的应用越来越广泛。文中设计了一款双向DC/DC变换器,实现正向工作时直流稳压电源对锂电池充电,反向工作时锂电池对直流稳压电源进行放电,使放电的能量可以返回到直流稳压电源中,从而实现能量回馈。实验表明,该变换器能够满足设计要求,具有十分重要的理论价值和现实意义。
Bidirectional DC/DC converters are more and more widely used in new energy and multi-port systems.In this paper,a bidirectional DC/DC converter was designed to charge lithium batteries by DC voltage regulator in forward operation and discharge DC voltage regulator in reverse operation,so that the discharged energy can be returned to DC voltage regulator in order to realize energy feedback.Experiments showed that the converter can meet the design requirements and had very important theoretical value and practical significance.
