Analysis of Closed Loop Control of High Voltage Gain DC-DC Boost Converter Using Voltage Multiplier Devices for variable voltage Applications
The high-voltage gain converter is widely employed in many industry applications, such as photovoltaic systems, fuel cell systems, electric vehicles, and high-intensity discharge lamps. This project presents a novel single-switch high step-up non isolated dc–dc converter integrating coupled inductor with extended voltage doublers cell and diode–capacitor techniques. This paper presents a dc-dc power converter integrated closed loop system to attain high stability factor in such a way to obtain, in a single conversion stage, the maximum energy extraction from photovoltaic panels, battery charging and discharging dynamic control, and high voltage step-up, also operating with softswitching capability. This review is mainly focused on high efficiency step-up DC/DC converters with high voltage gain. The results are obtained through Matlab/Simulink software package.
