Analysis and Comparison of Impedance Source Inverter with different suitable PWM approaches

Impedance source converter (ZSI) has improved features like efficient power conversion and reduced dependence on voltage source inverter (VSI), which makes it a good alternative for various distributed generating power applications. The concept of ZSI is well established and depends on the zero states found in the PWM technique of a VSI. In terms of boosted output voltage, THD of line current, voltage stress, shoot through state generation and converter gain, this paper examines a three-phase ZSI with maximum constant boost control method (MCBC) maximum boost control (MBC) and simple boost control (SBC) . The simulation results have been shown to verify the theoretical findings.
