The power electronics plays a main role in interconnecting the renewable energy sources to the grid. This research paper discusses a novel switched inductor cell combined with a switched capacitor cell-based quasi-switched-boost inverter (SL-SC-based qSBI) topology which can be used for renewable energy applications. This boost inverter topology is capable of providing a boosted AC voltage with high voltage gain and greater EMI immunity in a single stage compared to conventional voltage source inverter (VSI). In addition, it does not require any dead time period in its switching states since shoot-through is permitted. Instead, shoot-through state is used to achieve a high boost. This paper presents the principle of operation, steady-state analysis of the proposed inverter, modulation strategy adopted to produce the firing pulses and provides the performance comparison with the existing qSBI topologies. A single-phase 113 V (rms) load voltage is obtained with the DC source voltage of 32 V and duty ratio of 0.22. It provides the boost factor of 6.4. The proposed topology is simulated in MATLAB/Simulink platform to validate the theoretical concepts and the results are presented in detail. |
