“…In the proposed SCMLI1, the switch per level ( N SW / N L ) is 0.8, which is lower than the CHB topology and topologies presented in [12, 14, 16, 17, 19–24]. The topologies presented in [9–11, 13, 14] requires a lower number of switches than the proposed SCMLI1. However, these topologies require more number of DC sources, and [9] requires more capacitors, too.…”

“…The reduced number of switches is the main benefit and a large number of used dc power supplies and capacitors are the main drawbacks of this topology. Some other interesting topologies have been suggested in [10–15]. The fewer number of switches of the presented topologies in [10, 11] and generation of negative levels without any H‐bridge in the topologies presented in [12–15] are the significant advantages of these topologies.…”

In this study, a novel multi‐source switched‐capacitor converter is proposed. In the proposed topology, the capacitor charging is carried out in a self‐balancing form eliminating the need for additional balancing circuits. After that, the design principle of the proposed inverter is discussed in details. A comparison study between the proposed topology and other existing topologies is provided next. According to this comparison, the proposed topology requires fewer components, such as DC power supplies, switches, capacitors, and diodes. Further, the simulation results for 15‐level and 127‐level and the experimental results for a 15‐level inverter are provided. The simulation and experimental results are in close agreement and verify each other.

This paper presents a comparative evaluation of multilevel DC link inverter of photovoltaic (PV) renewable energy system using either symmetrical or asymmetrical dc sources. The four units of dc source can have the same dc voltage level, ie 81.32 V, resulting in symmetrical dc sources. The asymmetrical dc sources consist of input dc voltages in binary sequence, 21.68 V, 43.37 V, 86.74 V and 173.48 V. The boost converters with maximum power point tracking (MPPT) capability which is regulated by perturb and observe (P&O) based control are connected between the PV panels and the four dc sources. The varying dc voltages from the PV panels are regulated to track the maximum power available regardless of the irradiance and temperature conditions. The symmetrical dc sources will facilitate the generation of 9 levels of staircase ac waveform rms of 230 V after the H-bridge inverter. Whereas, the asymmetrical dc sources are able to produce 31 levels of staircase ac waveform also with rated rms 230 V. Detailed analysis and comparison on the powers, ac output voltage, output current, total harmonic distortions, and MPPT achievement are described.
