Abstract

Single-phase switched-capacitor multilevel inverters are an excellent alternative for low-power applications as they provide high voltage gain. However, their control and modulation are not simple due to the particularity of these topologies. Finite Control-Set Model Predictive Control (FCS-MPC) has therefore emerged as an attractive control alternative for these inverters. This article seeks to establish guidelines for the implementation of FCS-MPC in this type of inverter. To that end, FCS-MPC is implemented in two topologies that have previously been described in the literature as well as in a new topology. The results establish excellent methodological guidelines for applying FCS-MPC in this family of inverters, that achieve high dynamic responses.
