To improve the voltage gain of step-up converters, the cascaded technique is considered as a possible solution in this paper. By considering the concept of cascading two Z-source networks in a conventional boost converter, the proposed topology takes the advantages of both impedance source and cascaded converters. By applying some modifications, the proposed converter provides high voltage gain while the voltage stress of the switch and diodes is still low. Moreover, the low input current ripple of the converter makes it absolutely appropriate for photovoltaic applications in expanding the lifetime of PV panels. After analyzing the operation principles of the proposed converter, we present the simulation and experimental results of a 100 W prototype to verify the proposed converter performance.

In this paper, a new transformerless buck–boost converter is introduced. The proposed converter voltage gain is higher that of the conventional buck–boost converter. In the presented converter, only one power switch is used. The switch voltage stress is low, therefore, the low on-state resistance of the power switch can be selected to decrease losses of the switch. The presented converter topology is simple, hence the control of the converter will be simple. The mathematical analyses and principle of the proposed converter are explained. The validity of the proposed converter is confirmed by the experimental results.
