Summary This paper presents a new structure for a quasi‐resonant switched capacitor multilevel inverter. This structure offers multiple features of the conventional multilevel structures. Moreover, regarding the provided output voltage levels, the proposed structure exploits a new quasi‐resonant basic module which helps to diminish circuit cost and complexity using fewer power components. In the proposed structure, the balancing of capacitors voltages is achieved by series and parallel connection with the voltage source and without the need to employ a complicated control system. In order to obtain higher voltage levels at the inverter ac side, a developed H‐bridge is used in which the basic module is extended horizontally in separate cells on either side. Through a quasi‐resonant inductor deployment in the basic module, current spikes of capacitors are filtered which overwhelms decreasing of capacitor value and also lengthening the capacitor lifetime besides decreasing electromagnetic interference (EMI). Coupled with extensive simulation studies, experimental analyses are conducted to validate the performance of the proposed 17‐level inverter.

“…More is the number of switches, DC sources, and diodes, more will be the cost of an MLI. Figure 10a shows the proposed RS MLI uses least number of switches compared to the wellknown MLIs 'T1' in Chattopadhyay and Chakraborty [22], 'T2' in Lee et al [23], 'T3' in Samadaei et al [24], 'T4' in Sun et al [25], 'T5' in Babaei et al [26], and 'T6' in Ye et al [27]. The proposed RS MLI and T6 have identical switch count for all N l , and due to which these can be a preferred alternative to the conventional MLIs in medium/high voltage applications.…”

Multilevel inverters (MLIs) are developed to meet medium voltage and high power applications in flexible power systems. The conventional configuration of multilevel inverter requires more switches and has limitation to its wide range application. This paper reports the performed work on 1-phase 7-level reduced switch multilevel inverter (RS MLI) in photovoltaic (PV) system. RS MLI configuration integration with PV system which uses less number of switching components for specified number of voltage output levels as compared to that of conventional multilevel inverter topology. To performed enhanced operation of PV cells and maximize the solar energy extraction an incremental conductance based maximum power point tracking scheme is used. To improve the quality of RS MLI output parameters mainly total harmonic distortion and switching losses, selected harmonic elimination based genetic algorithm method is consider for control the gating pulse of PV based RS MLI. This work is performed using MATLAB/SIMULINK software. Keywords Reduced switch multilevel inverter (RS MLI) • Maximum power point tracking (MPPT) • Incremental conductance (IC) • Genetic algorithm (GA) • Total harmonic distortion (THD)

“…Even though it has a reduced number of isolated dc sources and voltage boosting, the inrush current is increasing during the charging of capacitors, and the size of the capacitor is increasing due to the self‐balancing operation. Asymmetric topologies are presented to increase the number of voltage levels with reduced blocking voltage and gate driver circuits . Another switched‐capacitor inverter module for 13L is proposed .…”

Summary In this paper, a new multilevel inverter topology is proposed for both symmetric and asymmetric configurations. The basic unit of the proposed topology consists of eight switches and three dc sources. In addition to this, the cascaded connection of the proposed topology is presented with various combinations of dc source values. The proposed topology is compared with other recent multilevel inverter topologies in terms of a number of power components and cost. To validate the performance of the proposed topology, the MATLAB/Simulink software is used, and results are discussed. Further, the prototype hardware is developed, and experimental waveforms are captured. The results of both simulation and experimental are presented, and it has a good agreement in terms of total harmonic distortion and dynamic performance for various loads.
