A multi-input inverter is capable of converting the direct current (DC) generated by multiple new energy sources into the alternating current (AC) required by power grids, effectively solving the problems caused by single new energy power supply such as low power supply reliability, poor power quality and significant power fluctuations. Based on the research status both at home and abroad, the topologies of multi-input inverters are classified into three categories according to the types of DC-DC converters and stages of power conversion, i.e., two-stage single-input DC-DC converters, two-stage multi-input DC-DC converters and single-stage multi-input inverters. A detailed discussion on various types of multi-input inverters is carried out, including their advantages and disadvantages, as well as the corresponding energy management under different application scenarios. Furthermore, a comparison of circuit complexity, control difficulty, cost and conversion efficiency among the multi-input inverters with different topologies is performed, providing a reference for further research and development in this field.
