Analysis and Control of a New Dual-input Impedance-based DCâDC Converter for Hybrid PV-FC Systems
A new dual-input DC-DC converter based on quasi-Z source converter is proposed in this study. This converter is a suitable option for efficiently interfacing two energy sources with a common load. The proposed topology, by integrating the switched-capacitor cell and coupled-inductor, provides a hi...

description |
A new dual-input DC-DC converter based on quasi-Z source converter is proposed in this study. This converter
is a suitable option for efficiently interfacing two energy sources with a common load. The proposed topology,
by integrating the switched-capacitor cell and coupled-inductor, provides a high step-up gain of voltage
conversion at small duty cycles. This topology works only by two switches and voltage stress across the
switches is low. Furthermore, continuous input current is one of the key features of the proposed converter
which makes it suitable for hybrid photovoltaic and fuel cell systems. In this research, it is attempted
to explain the operating principles, steady-state analysis, control and modulation for the proposed
converter under continuous inductor current mode. The merits of the proposed converter are presented
compared with those of other dual-input converters. Finally, simulation results from MATLAB\Simulink
are presented and experiments with a 150W prototype are performed to investigate the performance and
effectiveness of the studied circuit. |
