“…However, these converters have the limitations of a small voltage gain and no isolation. A Z-source inverter [24] has been presented for fuel cell applications, but three-phase inverters operate with hard switching and do not implement electrical isolation. Although many papers [25], [26] have introduced high-frequency link inverters to minimize the transformer volume or the dc link capacitors, complexity and component cost detract from these topologies.…”

This paper presents a new isolated soft-switching bidirectional buck-boost inverter for fuel cell applications. The buckboost inverter combines an isolated DC-DC converter with a conventional inverter to implement buck-boost DC-DC and DC-AC conversion. The main switches achieve zero voltage switching and zero current switching by using a novel synchronous switching SVPWM and the volume of the transformer in the forward and fly-back mode is also minimized. This inverter is suitable for wide input voltage applications due to its high efficiency under all conditions. An active clamping circuit reduces the switch's spike voltage and regenerates the energy stored in the leakage inductance of the transformer; therefore, the overall efficiency is improved. This paper presents the operating principle, a theoretical analysis and design guidelines. Simulation and experimental results have validated the characteristics of the buck-boost inverter.

This venture "Simulat ion and Imp lementation of Γ-Z-Source Inverters" is made out of Voltage-sort Γ-Z source inverters are proposed in this letter. They utilize a remarkable Γ -mo lded impedance arrange for boosting their yield voltage notwithstanding their standard voltage buck conduct. Contrasting them and different topologies, the proposed inverters utilize lesser parts and a coupled transformer for delivering the high-pick up and regulation proportion all the wh ile. The got pick up can be tuned by changing the turns proportion γΓZ of the transformer inside the limited scope of 1 < γΓZ ≤ 2. This prompts to lesser twisting turns at high pick up, as compared to other related topologies.

“…Quasi Z-source inverters, extended boost quasi Z-source inverters, and improved Z-source inverters are a few examples of this type [8][9][10]. References [11][12][13][14] enumerate applications for the Z-source inverter in the field of renewable energy sources and adjustable-speed drives. Multilevel Z-source inverters are discussed in references [15,16], which have all the advantages of the Z-source inverter and produce multilevel output.…”

This paper presents a novel approach for power generation from rotating machines in textile mills using externally coupled repulsive magnets and a new stepped DC coupled Quasi Z-inverter. Power is obtained as a byproduct of the effective harnessing of rotational energy with the use of repulsive magnets. This derived power is stored in a battery arrangement and is retrieved, buck/boosted, and converted to multilevel AC voltage with the new stepped DC coupled quasi Z-inverter. The proposed inverter is powered by isolated voltage sources, uses fewer switches, and produces less distortion in the resulting multilevel voltage compared to its counterpart, and thus reduces the filter requirements.The derived AC power from the system can be used for light-load applications in textile mills, thus compensating for the energy demands. Simulation of the entire proposed setup is performed in MATLAB/Simulink and the results are presented. The repulsive force produced by the magnets is assessed with K & J Magnet software. To validate the simulation, experimentation is done using rotating machines available in the laboratory. The prototype model of the stepped DC coupled quasi Z-inverter is used to study the performance of the system and the results are evaluated. The optimum modulation index is identified for different numbers of sources at the input.
