“…TSV pu is the ratio of TSV to the peak value of AC output voltage. The proposed topology and the one presented in [16] have the minimum TSV pu . The proposed topology needs 14 IGBTs, but as it has two bidirectional switches and six unidirectional switches, the number of drivers required is reduced to nine.…”

“…The proposed topology needs 14 IGBTs, but as it has two bidirectional switches and six unidirectional switches, the number of drivers required is reduced to nine. Among single DC source topologies, that presented in [16] has fewer switches than the proposed one, but it uses five capacitors as compared to three in the proposed topology. Further, it has no voltage-boosting ability.…”

“…Even though the device components are reduced, the total standing voltage (TSV) is high for the circuit. An 11-level inverter was proposed in [16] using twelve switches and a total of five capacitors using an auxiliary circuit for the complex control logic. For the same number of levels, the authors of [17] reduced the number of switches to 10, but it requires a large number of capacitors and diodes (nine capacitors and nine diodes).…”

An 11-level switched-capacitor multilevel inverter (SCMLI) with 2.5 times boosting feature is presented in this paper. It can produce an 11-level output voltage waveform by utilizing 14 switches, 3 capacitors, 2 diodes, and 1 DC source. Only nine driver circuits are needed as the topology has three pairs of complementary switches and two bidirectional switches. It has inherent capacitor self-balancing property as the capacitors are connected across the DC voltage source during several states within a fundamental cycle to charge the capacitors to the input voltage. A detailed comparison shows the effectiveness of the proposed topology in terms of the number of switches, number of capacitors, number of sources, total standing voltage (TSV), efficiency, and boosting ability with the state-of-art recently proposed circuits. Subsequently, the performance of the proposed SCMLI is validated experimentally utilizing the nearest level control (NLC), a fundamental frequency-based switching technique.

This work presents hysteresis control applied to UXE-type inverter topology with a PI (Proportional Integral) controller, where thegains are derived by Particle Swarm Optimization (PSO). The investigated UXE inverter can generate a thirteen level output voltage waveform, which results in lower switching losses. It can boost the output voltage to 1.5 times the applied input DC source voltage. Satisfactory inverter operation is ensured by employing twelve-band hysteresis current control. The tuning of the PI controller required for the closed-loop hysteresis current control is achieved by nature-inspired PSO algorithm. A comparative analysis is also performed after obtaining the results applying natureinspired PSO and conventional Ziegler Nichols (ZN) methods. The effectiveness of the control strategy is verified in the MATLAB Simulink and further validated in experimentusing TMS320F28379D and also with Typhoon Hardware in Loop Technology.
