“…That is, considering Regarding the number of capacitors necessary to produce the appropriate DC-link ripple values, the CHB-SDC structure, besides presenting a smaller number of capacitors than single-phase structures, presents total capacitance values, on average, six times lower than the classical CHB topology [27,[32][33][34][35]. Some studies claim that these values can be up to 10 times lower [28,[36][37][38], demonstrating evident superiority of three-phase structures over single-phase structures in terms of the total capacitance.…”

This paper proposes a new cascaded multilevel converter topology based on three-phase H bridge cells with a common DC-link structure. The proposed multilevel converter topology main advantages, compared with literature renowned multilevel converters topologies, are discussed in the paper, such as modularity, construction, implementation cost, and DC voltage ripple mitigation. Despite presenting an elementary structure and easy implementation, the use of classic PWM switching strategies is not feasible for this topology, causing the appearance of several short-circuit states between its capacitors. Thus, a graph theory algorithm combined with a model predictive control is also proposed in this work to identify and avoid the new cascaded multilevel converter short-circuit switching states and, concomitantly, guaranteeing the converter output power quality. In order to validate the presented topology applicability, a low voltage synchronous static compensators (STATCOM) with an optimal switching vector model predictive control (OSV-MPC) is implemented in a hardware-in-the-loop platform. The real-time experimental results prove the proposed multilevel topology and the OSV-MPC control strategy effectiveness.

The aim of this paper is to evaluate the benefits that can be achieved by operating the connection inverters of the distributed energy resources as active power filters in LV distribution networks. The use of photovoltaic inverters to compensate zero sequence currents, arising from unbalances among phases, can improve the efficiency of the distributed system by means of reducing the total amount of losses. For that purpose, a typical load in parallel with a distribution network where a photovoltaic inverter is connected has been simulated. The reductions in the distribution power losses and compensation of zero sequence currents have been demonstrated.
