Multilevel inverters are increasingly considered in integrated generation systems (IGSs) due their significant advantages and low voltage output harmonics content. In this paper a switching neural network (SNN)-based method to provide the switching pattern for harmonics reduction is proposed. We perform the implementation of this new paradigm to establish the switching pattern for a five level three-phase inverter. The provided results as well as the main guidelines for SNN software and hardware implementation show the significance of this approach.

“…In these cases the multilevel converter is a more robust option and has several advantanges like: smalest voltage aplied in power switches and higher quality output voltage [5], [6], [7], [8], [9], [10], [11]. The CCMLI has very significant advantages for connecting photovoltaic systems.…”

“…The proposed control calculates PWM reference to contain the common mode voltage required for compensation. However, this is performed indirectly, unlike what happens in other techniques applied to this problem [5], [6], [12]. It also conducted an analysis of operational limits admissible for this PV system, where even with these imbalances should be possible the conection with power grid keeping maximum power transfer.…”

This paper presents a control strategy applied to a three-phase Cascaded Cell Multilevel Inverter (CCMLI) feeded by photovoltaic panels and connected to power grid, able to compensate imbalances between cells and phases. The technique consists in indirectly obtaining common mode voltage and adding a control loop power control in the conventional structure. Following in this analysis, it will be presented a method for determining the operational limits of a photovoltaic system to support the most diverse conditions of imbalances. Finally, simulation results of a seven levels CCMLI are presented, with string topology without boost stage to demonstrate and validate the proposed technique.

“…Authors in [8] have used a control technique with similar basis as [7], and experimental tests have been provided to verify the results. The same principle is employed in [9], but Space Vector Modulation (SVM) technique is adopted instead of Phase shifted PWM (PSPWM), resulting in a more efficient control system. Reference [10] has utilized modified Ripple-Correlation Control to control 5-level CHB inverter, leading to a very good dynamic response.…”

In this paper, a control method based on the derivative of power is introduced for single-stage singlephase grid-connected cascaded H-bridge (CHB) photovoltaic inverters. The proposed scheme uses solar arrays derivative of power with respect to current to track maximum power point of each array individually. Using this method along with hybrid modulation technique allows utilization of CHB cells up to their full potential. The control system has a simple structure, and is inherently able to stabilize the system in heavy mismatching conditions where the modulation index goes higher than unity. The effectiveness of the proposed technique is verified by simulation and experimental results.
