近年来，针对交流模块系统的光伏模块集成转换器已开发出多种拓扑结构。在这些拓扑结构中，反激式功率转换器由于其配置和控制的简单性而受到关注。本文提出了反激式光伏组件集成变换器的双模式开关控制方法。所提出的切换控制方法交替改变 DCM 和 BCM 的操作模式。预计通过传导模式的改变可以实现效率和传输功率量方面的高性能。通过仿真和实验结果验证了所提出的开关技术的有效性。
In recent years, many topologies have been developed as PV module integrated converter for AC module system. Among these topologies, the flyback-type power converter have been occupied the attention due to its simplicities on configuration and control. In this paper, dual mode switching control method for flyback-type PV module integrated converter is proposed. Proposed switching control method changes the mode of operation in DCM and BCM alternatively. It is expected that the high performances in efficiency and transferred power quantity can be achieved through the conduction mode change. The efficacies of proposed switching technique are validated by simulation and experimental result.
