The solar PV source is getting more attention due to abundant availability and cost effectiveness but the generated power has low DC voltage. Hence, Voltage step up is becoming the most important task for researchers and engineers due to more adaptability of renewable power generation sources into daily life. This paper is dedicated to step-up the voltage level by using a dc-dc converter domain with the quasi-Z-source (QZS) network. This paper has discussed QZS dc-dc converter with a switched capacitor, active switched-capacitor/switched-inductor QZS converter, a dc-dc converter with modified QZS network and modelled in MATLAB Simulink for experimental study and result in analysis is done at different duty cycles. The obtained results are compared along with one another for finding the voltage boost up the capacity of each converter topology.
