摘要

将直流电转换为交流电的需求是由于与电力分配系统相连的可再生能源发电的日益发展。功率转换是通过功率逆变器进行的，其中三相四脚逆变器除了作为电力转换器外，还可以稳定提供给负载的输出电压。配电网上的电压由于与不平衡三相负载的连接而产生不平衡。本文介绍了一种使用LC滤波器的四腿三相逆变器，使用MPC控制产生正弦输出电压并平衡电压。仿真结果表明，负载平衡时，输出电压的THD为0.3% ~ 0.5%，负载不平衡时，输出电压的THD为0.2% ~ 1.7%，电压不平衡百分比为0.1% ~ 0.9%。

Three-phase Four-leg Inverter LC Filter Using FCS MPC

The need to convert electric power from dc to ac is due to the growing development of renewable energy generation connected to an electric power distribution system. The power conversion is carried out with power inverters where a three-phase four-leg inverter, apart from being an electric power converter, turns out to stabilize the output voltage supplied to the load. The voltage on the distribution network can experience imbalance due to connection with an unbalanced three-phase load. This article presents a four-leg three-phase inverter using an LC filter using an MPC control to produce a sinusoidal output voltage and balance the voltage. From the simulation results, it is obtained that when the load is balanced, the THD of the output voltage is 0.3% - 0.5%, while in unbalanced load conditions, the THD of the output voltage is 0.2% - 1.7%, with a percentage of voltage imbalance of 0.1% - 0.9%.
