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.
In this article, a parallel structure of inverter is proposed for systems using photovoltaic panels.
To produce a five-level inverter output voltage four triangular carrier signals with an equal phase shift of 90º are required. Due to symmetry of phases, the modulating scheme is shown only for single phase. For simplicity the gate signals for only upper switches of HBCs are shown as second switch in each leg is complementary in nature.
Currently, multi-level inverters are preferred over conventional two or three-level inverters due to their confirmed advantages. Actually in the literature there are many papers which present and discuss various topologies of multi-level inverters and mention the benefits of their structures .
Hence, multilevel inverter (MLI) designs have gained popularity for GCPV applications during the last decade. In addition to conventional topologies some new and different MLI topologies such as hybrid, RDC, T-type, active-NPC, asymmetric and modular MLI can also use for grid-integrated PV applications 14, 16, 17, 18.
Neutral-point-clamped (NPC) inverters are the most widely used multilevel inverter topology in high power applications. Figure-1 shows some variants of this topology. Figure-1ab shows the topology of a three-level and five-level inverter respectively.
