摘　　要：级联H桥变流器在大容量储能、电能质量治理、高压电机驱动领域得到了广泛的应用,对于未来大容量的电动汽车集群的并网具有很好的应用前景。但其拓扑结构中的多直流侧存在不平衡问题,制约了级联H桥变流器在电动汽车集群应用中的发展。通过对级联H桥变流器用于电动汽车集群的接入方式进行研究,建立了级联H桥变流器的数学模型,进一步提出了其直流电压平衡控制方法。最终通过仿真进行了验证,得出该研究提高了电动汽车集群的并网效率和可靠性。Cascaded h-bridge converter has been widely used in the fields of large-capacity energy storage,power quality control and high-voltage motor drive.However,the unbalanced multi-dc side in the topology restricts the development of cascaded h-bridge converter in the application of EV cluster.By studying the access method of cascaded H-bridge converter for electric vehicle cluster,the mathematical model of cascaded H-bridge converter is established,and the DC voltage balance control method of cascaded hbridge converter is proposed.Finally,it is verified by simulation.
