“…The prevalent topologies found in multilevel inverters are the Neutral-Point-Clamped (NPC) (13,14) Flying-Capacitor (FC) (15,16), and Cascaded H-Bridge (CHB) (17,18). Due to the smaller size requirements of DC sources, NPC structures are an exciting option for interfacing DGs with grids (19).…”

Grid-tied Neutral-Point-Clamped (NPC) inverters have been widely used in various applications recently. A superior control method is required to achieve the desired performance of a grid-connected NPC inverter. Accordingly, a second-order sliding mode control (SOSMC) method, which is designed in the stationary frame, is utilized for achieving this aim in this paper. The super-twisting second-order sliding mode control is used for solving the chattering problem of conventional first-order sliding mode control (FOSMC). In comparison to control methods which are applied in rotation frame, this method is not required transformation from rotating frame to a-b-c frame and vice versa and decoupling of d and q components. The Lyapunov stability analysis is used for designing of this controller. The performance of proposed method is evaluated by simulation results implemented in MATLAB/Simulink software. The performance of the SOSMC is also compared with FOSMC. The results show that the incorporation of SOSMC can improve current reference tracking of the NPC inverter in different scenarios.

“…Among the available modulation schemes for the switching PWM has many advantages such as lower power loss with respect to switching and snubber while maintaining the dv/dt rating quite small. As for the fundamental frequency, there are two well-known switching techniques, one is Selective Harmonic Elimination (SHE) [24] and the other is NLC [25][26][27][28][29][30]. In the SHE technique, increasing the number of output levels creates a large volume of offline computational costs with respect to switching angles and their storage.…”

In this paper, a novel voltage-boosting switched-capacitor multilevel inverter (SCMLI) capable of producing 19 voltage levels using a combination of only 10 switches, 4 diodes, 2 capacitors, and 2 DC sources has been proposed. The main features of the proposed topology are 1) utilization of a very low number of devices, 2) very low Total Standing Voltage (TSV) equal to 6.55 and 3) self-balance property of the capacitors' voltages. In order to provide the IGBTs of the circuit with the desired switching signals, the Nearest Level Control (NLC) method has been adopted. To clarify the benefits of the designed topology as to the total quantity of switches, DC sources, capacitors as well as the total standing voltage (TSV), and converter boosting, a thorough comparison has been carried out versus the recently published 19-level topologies. Also, for the purpose of performance evaluation and validation, the suggested topology has been tested against various loads through an experimental setup in the laboratory using TMS320F28379D DSP as the processor. The comparative, simulation, and experimental results all imply the superiority of the proposed topology against its predecessor counterparts.

“…So, researchers introduced several approaches to achieve this purpose. One of the approaches is to use a coupling inductor or transformer in a multilevel inverter structure [10][11][12][13][14]. However, in low frequencies (lower than 50 Hz), the inductors and transformers make the system drastically bulky and expensive.…”

This paper presents a new symmetrical switched-capacitor (SC) multilevel inverter topology which can convert the input DC voltage to a step-up multilevel AC waveform on the load. This proposed multilevel inverter consists of one T-type and several cross-capacitor modules. The structure of the generalized multilevel inverter is such that the peak inverse voltage (PIV) remains constant as the number of crosscapacitor modules increases which leads to reduce the total standing voltage (TSV) of the switches and cost function compared to other traditional topologies. The introduced structure can inherently generate the positive, negative, and zero voltage levels on the output without the back-end H-bridge section. The capacitor's voltages in the T-type and cross modules are inherently balanced, simplifying the control system under the nearest level control (NLC) switching strategy. To verify the performance of the proposed topology, several simulations and experimental results for a type 13-level inverter are provided by MATLAB and TMS320F28379D DSP, respectively.
