Abstract

The ongoing electrification of the transport sector raises demands for new power electronic solutions. As a consequence, modular converter structures are state of the art for fast charging, since high power and short charging times are required. This work presents a modular multiport DC-DC converter which has the capability to decrease the cost and size of the required charging station. Furthermore, design guidelines for the investigated topology are presented. The analysis is validated with a three port isolated DC-DC converter with separated loads.

隔离式多端口转换器作为电动汽车直流快速充电器的低成本解决方案
交通运输部门的持续电气化提出了对新的电力电子解决方案的需求。因此,模块化转换器结构是快速充电的最新技术,因为需要高功率和短充电时间。本文提出了一种模块化的多端口DC-DC变换器,该变换器能够降低所需充电站的成本和尺寸。此外,还提出了所研究拓扑的设计准则。用负载分离的三端口隔离DC-DC变换器验证了分析结果。
