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 ...

Neutral point clamped quasi-impedance-source inverter
2011 7th International Conference-Workshop Compatibility and Power Electronics (CPE), 2011In this paper a new modification of a three-level neutral-point-clamped inverter is presented. The proposed topology combines the advantages of the three-level neutral-point-clamped full-bridge inverter with those of the quasi-impedance-source inverter.

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.

Impedance source inverter based AC-AC converter system
International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2011), 2011This paper presents a new topology of uninterruptible power supply (UPS) by using a Z-source inverter, where a symmetrical LC network is employed to couple the main power circuit of an inverter to a battery bank. Using passive diode rectifier is known to constrain the converter to operate in only the forward power transfer mode, and generally support ...

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.
