Comparative study between ZSI, SBI and CFSI

Different topologies of boosting circuits are available nowadays. Z-Source Inverter(ZSI), Switched Boost Inverter(SBI) and Current Fed Switched Inverter(CFSI) connects an impedance network in between the source and the load. These circuits are of dc-ac inversion type, can operate in both buck-boost modes and possess advantages over traditional V-source and C-source Inverters. This paper includes a comparative study between ZSI, SBI and CFSI. The three circuits are simulated under MATLAB/Simulink platform for same input.
