The present paper focuses on the use of the Multilevel Current Rectifier topology as an interconnection element between PV systems and the network or loads. In order to properly use the converter in connection with the PV system, several subjects such as the compatibility with the maximum power point tracking and the compatibility between the converter and the PV array must be taken into account. Compatibility between the converter and the PV array can be achieved by ensuring at least the maximum power point is a point that the converter can work with. In this sense, this work focuses on the operating conditions to guarantee the compatibility with the PV array. The main results are an analytical and experimental characterization of the operating range of the system using the Multilevel Current Rectifier. This operating range has a precision of $1\%$. Leading to the conclution that not only the converter is a viable option, but also that the theory and methodology used can be extrapolated to another topologies.

本文重点介绍多电平电流整流器拓扑作为光伏系统与网络或负载之间的互连元件的使用。为了正确使用变流器与光伏系统连接，必须考虑与最大功率点跟踪的兼容性以及变流器与光伏阵列之间的兼容性等几个主题。转换器和光伏阵列之间的兼容性可以通过确保至少最大功率点是转换器可以工作的点来实现。从这个意义上说，这项工作侧重于运行条件，以保证与光伏阵列的兼容性。主要结果是使用多电平电流整流器的系统工作范围的分析和实验表征。该操作范围的精度为$1\%$. 得出的结论是不仅转换器是一个可行的选择，而且所使用的理论和方法可以外推到另一种拓扑结构。
