Background: The traditional embedded impedance-source inverter topology exhibits the disadvantages of low boost factor and higher cost due to additional PV sources. Objective: This research paper deals with the performance improvisation of embedded impedance-source inverter topology called Switched-Inductor DC-link Embedded Zsource Inverter (SL-DC-link EZSI). Switched inductor concept is employed to the reduced source DC-link EZSI to achieve the strong boosting ability in terms of short shoot-through period. Results: Simulation of PV powered SL-DC-EZSI fed induction motor drive is performed. The operating principle and the topological analysis are given. Boost factor performance, capacitor voltage and DC-link voltages as a function of shoot-through ratio of the SL-EZSI system is compared with the proposed SL-DClink EZSI system and the results are presented. Conclusion: PV powered Switched inductor DC-link EZSI topology is proposed and the results are presented. The propounded topology has the characteristics of high boost ratio, minimum shoot through period, reduced voltage stress and low cost.
