Zegrari, A. Taouni, A. Ouchatti. 2020. A Nine-Switch Nine-Level Voltage Inverter New Topology with Optimal Modulation Technique.
A single-phase transformerless PV inverter topology can be categorized based on several factors. These include the number of input dc-link voltage (single, double, etc.) and the fundamental origin of topology (H-bridge, NPC, etc.) .
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.
