In , a coupled structure switched capacitor-based boost thee phase multilevel inverter with 1.2 kW rated power is presented. In this inverter, a traditional three phase bridge is fed by a SC tripler unit. The capacitor voltage ripple is reduced using an improved virtual space vector modulation (SVM) method.
However, at low power, the amplitude of pulsed currents is low, and these inverters can be a good option due to special features such as reduced component counts and voltage-boosting capability. This article presents an expendable three-phase multilevel inverter based on switched-capacitor cells which can boost the input voltage.
Another switched capacitor-based, three-phase multilevel inverter was proposed in . This topology has twenty-four power switches, which can generate seven-level output line voltages. Although this inverter can boost the voltage up to three times, its components are high.
A compact three-phase multilevel inverter with reduced component count for low voltage application is proposed in . In this inverter, the number of components has been reduced, but three DC sources are used in its structure.
In recent years due to the massive development in renewable energy-based power generation systems, three-phase inverters with boosting capability play a significant role in connecting low-voltage renewable energy sources like photovoltaic (PV) to the grid .
In this inverter, a traditional three phase bridge is fed by a SC tripler unit. The capacitor voltage ripple is reduced using an improved virtual space vector modulation (SVM) method. The overall standing voltage is decreased by using a smaller number of devices in terms of the number of series linked capacitors.
