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 ...

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 ...

Series Switched Quasi Impedance-Source Inverters with Improved Boosting Ability
2021 IEEE 4th International Conference on Computing, Power and Communication Technologies (GUCON), 2021Impedance-source inverters (ZSIs) are getting more popular in renewable energy generation over conventional inverters due to their inherent boosting characteristic and shoot-through invulnerability. However, most of the ZSI expansion abilities are somehow restricted by the component stresses and inferior performance, particularly at extreme duty ...
