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.

A soft-switching boost half-bridge converter with high voltage gain and low input current ripple is proposed in this paper. In the proposed converter, a coupled inductor is used at the boost converter stage to reduce the input current ripple. The half-bridge converter stage provides soft-switching operation and high voltage gain. Also, the reverse-recovery problem of output diodes is significantly alleviated by utilizing the leakage inductance of the transformer. Due to the soft-switching operation of all switching devices, the switching loss is significantly reduced and the high efficiency is obtained. The feasibility and performance of the proposed converter were verified on an experimental prototype
