A single-phase cascaded multilevel inverter based on a new basic unit with reduced number of power switches. IEEE Trans. Ind. Electron. pp. 922-929. R. Majdoul, A. Touati, A. Aitelmahjoub, M. Zegrari, A. Taouni, A. Ouchatti. 2020. A Nine-Switch Nine-Level Voltage Inverter New Topology with Optimal Modulation Technique.
In, a single-phase seven-level inverter with integrated boost circuit is proposed, there is no switch multiplexing and can be regarded as a two-stage topology. Thanks to the front-end boost circuit, system voltage gain is improved significantly. However, the allowed input voltage range is very narrow, which is not suitable for PV applications.
Generally, multilevel inverters are classified into three categories: Neutral-point-clamped (NPC) inverters (see Figure-1), Flying capacitor (FC) inverters (see Figure-2), and Multi-cell multilevel (ML) inverters (see Figure-3). Neutral-point-clamped (NPC) inverters are the most widely used multilevel inverter topology in high power applications.
Certainly, multilevel inverters also have disadvantages such as: the number of semiconductors and voltage sources (isolated or not) necessary for the operation of these inverters, which increases with the increase in the required number of voltage levels.
