This paper presents the experimental investigations of Switched Inductor cell (SL-FLCHBqSBI) based Five-Level Cascaded H-Bridge quasi Switched Boost Inverter for Renewable Energy (RE) applications. The SL-FLCHBqSBI topology is based on the ripple input current Switched Inductor Boost Inverter (SLBI) structure which is available in the literature. In this work, a stiff DC voltage of 36 V is taken as input to deliver a power of 100 W across a resistive load is designed. The control signals for the active devices are generated using Phase-Shifted sinusoidal Pulse Width Modulation (PS-PWM) modulation technique. The SL-FLCHBqSBI topology provides a higher voltage gain of 2.83 compared to the conventional topologies for a low duty ratio. The simulation is performed in MATLAB/Simulink environment and the simulation results are presented. A hardware set up is implemented and experiments are carried out to check the consistency of the theoretical concepts with the working of the proposed topology in practical.
