“…Both unidirectional and bidirectional switches are used; ie, S l 2 and S r 2 are bidirectional switches, and S l 1 , S l 3 , S 1 , S 2 , S 3 , S 4 , S r 1 , and S r 3 are unidirectional switches where the bidirectional switch comprises of an insulated‐gate bipolar transistor (IGBT) with four diodes connected in antiparallel fashion allows the bidirectional flow of current. Three types of structures for bidirectional switches are studied in the studies of Agrawal and Jain according to Figure B, ie, IGBT switch with four antiparallel diodes, common emitter, and common collector. Although the ON‐state voltage drop reduces in common collector type of bidirectional switch but it requires two IGBTs with the two gate driver circuits whereas in common emitter bidirectional switch, one gate driver circuit is required instead.…”

Summary In this research work, a generalized structure of multilevel topology is proposed that can be extended by cascading the modules. Proposed modular topology is modified T‐type structure that requires comparative reduced number of power components than other existing structures of multilevel inverter. Each module encompasses of three DC sources and 10 power switches. Both positive and negative voltage levels can be generated without the use of H‐bridge inverter; thus, lower voltage rating power switches are employed for proposed modular topology. To generate the output voltage levels, the nearest level control is implemented on the experimental setup using dSPACE 1103 controller. To verify the performance of the proposed inverter, experimental validation of various topologies based on different algorithms is performed to generate 15‐level, 17‐level, 27‐level, and 31‐level at different load conditions. Moreover, different state‐of‐art topologies are compared with proposed topology in terms of the required number of voltage levels, DC sources, power switches, driver circuits, and total standing voltage.

Summary The proposed work shows a novel multilevel inverter (MLI) configuration to generate a large number of voltage levels with lesser number of power switches. The proposed generalized inverter comprises basic cells cascaded to each other. Each cell of the proposed inverter can generate three‐level AC voltage using the power switches of the same rating. Both single‐phase and three‐phase MLI configurations are possible for the proposed structure. To validate the performance of the proposed MLI configuration, a nine‐level inverter using six power switches and a 27‐level inverter using nine power switches are designed and simulated in the MATLAB/Simulink environment. An experimental prototype is developed in the laboratory, and the experimental results are presented to verify the simulated results. Further, to validate the effectiveness of the proposed multilevel inverter, a comparison of the proposed MLI with recently proposed multilevel inverter has been incorporated in a detailed manner.

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.
