A family of cost-effective magnetically-coupled impedance source inverters
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017This paper presents a family of cost-effective magnetically-coupled impedance source inverters for renewable energy systems. The inverters are derived from magnetically-coupled impedance source networks, featuring low cost and no ground leakage current when used in PV system. The numbers of required semi-conductor switches is reduced.

Comparative analysis of various impedance source inverters
2016 International Conference on Automatic Control and Dynamic Optimization Techniques (ICACDOT), 2016Use of renewable energy sources has been increasing day by day because of its availability in frequent manner and of low cost. These sources are coupled with the various converters to convert dc to ac, ac to dc, ac to ac and dc to dc. Renewable energy sources produces dc output voltage hence, it must be converted into ac output voltage according to ...

Development of Impedance-Source Inverter Using SiC-MOSFET
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2018Impedance-source inverter using SiC-MOSFET was studied. A 3-kW laboratory level inverter had the efficiency of about 96 % at the condition of output boost ratio G of 1.77 (boost ratio B of 2.5), output power of 3.16 kW and input voltage of 240 V. At lower G case of 1.32 (B of 1.61), the efficiency of impedance-source inverter was increased by 97.4 ...

Analysis of magnetically-coupled impedance source three-phase four-switch inverters
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017In this paper, magnetically-coupled impedance source (MCIS) three-phase four-switch inverters are introduced for renewable energy applications. This inverter utilizes two single-phase MCIS inverters to obtain a three-phase output, where less component-count is achieved in order to reduce the inverter volume.

Single-Phase Transformerless Grid-Connected Impedance Source Inverter
2018 International Electrical Engineering Congress (iEECON), 2018This paper presents a design and control of single-phase transformerless grid-connected impedance source inverter. The conventional tranformerless grid-connected inverters might cause the DC offset in the injected currents to the grid due to the leakage current from deteriorated PV panels.
