“…The efficiency of the converter is limited by the active power switches, diodes, capacitors, and inductors serial resistances and therefore the cascaded boost converters due to their more components numbers are not recommended. 21,22 In some studies, researchers use an inverter to convert this DC voltage to the AC voltage and in the next step, by a transformer an AC voltage with higher magnitude is obtained for AC utilizations and then by a rectifier block, the desired DC voltage is obtained for DC applications. Although these topologies can obtain the high DC gains, these converters are heavier and more expensive and have lower efficiencies based on the high number of the middle blocks and the components especially the transformer.…”

Many of the photovoltaic (PV) panels generate the low amounts of the voltages under the limited values of the powers. In order to increase these voltages to be applicable for grid utilization, DC-DC boost converters are used. A novel nonisolated transformer-less switched-capacitor-based DC-DC power boost structure is combined with the quadratic converter in this study. The proposed converter has many advantages such the low-voltage stresses on the power components, higher voltage-gain, and ability to supplying the load under the low amounts of the switching time intervals. These features lead to fewer amounts of the currents for the power components in the topology for the continuous conduction mode which means less dynamic losses and higher efficiency. Another advantage of the proposed converter is including only one power switch that simplifies the controller design for implementation purposes. A comprehensive mathematical analysis is presented and simulation with MATLAB/SIMULINK and implemented hardware test results confirm the theoretical investigations.
