Abstract

The charging infrastructure for Electric Vehicle (EV) has major demands in recent years. Considering Solar Photovoltaic (PV) as the input reduces dependency of Power Grid. This literature presents Modified Z-Source Inverter (MZSI) that provides boosted output to charge the battery through charging unit and supplying to grid. The dc-ac conversion stage is reduced from multi stage to single stage with the help of Z-Source Inverter (ZSI). In this article, three ports such as PV has input source, Grid and Battery charging unit are considered as output ports with MZSI as a converter. Multiple ports has been created by splitting the capacitors across switches in MZSI for connecting multiple battery charging unit. This topology operates in different modes such as PV to Grid, PV to Battery, Grid to battery and Battery to Grid. In this work, lithium ion battery is considered for the analysis purposes. The results and analysis carried out in MATLAB/Simulink and the results are obtained which shows that multiple vehicles can be charged with this topology.

多端口电动车充电器改进型z源逆变器的设计与实现

近年来，电动汽车对充电基础设施有较大的需求。将太阳能光伏发电作为输入，降低了对电网的依赖性。本文介绍了改进的z源逆变器(MZSI)，它提供了增强的输出，通过充电单元给电池充电并向电网供电。在z源逆变器(ZSI)的帮助下，直流-交流转换阶段从多级减少到单级。本文考虑PV有输入源、Grid和Battery充电单元三个端口作为输出端口，MZSI作为变换器。通过在MZSI的开关上分割电容器创建了多个端口，用于连接多个电池充电单元。这种拓扑以不同的模式运行，如光伏到电网、光伏到电池、电网到电池和电池到电网。在这项工作中，锂离子电池被考虑用于分析目的。在MATLAB/Simulink中进行了结果和分析，结果表明该拓扑结构可用于多辆汽车。
