PROJECT TITLE :
An Impedance Networks Boost Converter with High-voltage Gain - 2017
An impedance network dc-dc boost converter is developed during this letter. Compared to the standard boost converter, it can reach a better voltage gain with fewer diodes and a little duty cycle (smaller than 33percent) and, meanwhile, avoid instability caused by saturation of its inductors, whereas the standard boost converters notice high-voltage gains at rather giant duty cycles (normally exceeding 50%) resulting in saturation of inductors. Furthermore, it will well fulfill the stringent industrial needs, particularly of renewable power systems. The proposed converter with continuous conduction modes is analyzed for different states of its parts. Then, it is shown how to work out its varied parameters. Finally, simulations and a 250-W prototype are conducted to verify the converter's effectiveness.
