  A high step up dc dc converter based on an isolated dc dc converter with
voltage multiplier cells for photovoltaic systems is essentially introduced in
this paper. The proposed converter can provide a high step up voltage gain. The
switch voltage stress and losses on semiconductors are significantly reduced
through this work. Furthermore, the proposed converter can reliably offer and
provide continuous input current which can be basically used for integrating
photovoltaic systems to convert 30 V to 480 V dc bus. The ripple on the input
current is minimized due to the isolated converter, and the proposed converter
is fed by a single input voltage. The operation modes and the characteristics
of the aforementioned converter are thoroughly analyzed. The components
selection, simulation results and experiment results are mainly verified by
using MATALB Simulink. Consequently, a 360 W hardware prototype is implemented
to validate the design and the theory.
