Description
ABSTRACT
In this paper, a non-isolated bidirectional dc-dc converter is presented. The proposed converter consists of voltage gain and reduced switching stress. High Gain DC-DC converter with their body diodes are employed in the proposed converter. The voltage gain of the proposed converter is higher than the previous. The Solar is the source of the Converter. The stress on converters devices and the efficiency of the proposed converter are discussed in this paper. Finally, the proposed converter prototype circuit is implemented to justify the validity of the analysis. In this proposal, the switching stresses and switching losses are somewhat reduced compared to Existing System. A Single Switch High Step-Up Converter
EXISTING SYSTEM
The Existing method was derived from the conventional Buck/Boost Converter. This system has more switching losses as well as switching stresses. And its gain value is also lows compared to the proposed converter.
PROPOSED SYSTEM
In the proposed system, A Single Switch High Step-Up Converter the High gain DC-DC converter is proposed. Here, the Solar module is taken as an Input for the converter. In this proposal switching losses and switching stress are also minimized. The overall efficiency of the converter increases with the converter. The gain and output variations are taken in the simulation. The high gain value gets in Matlab Simulink.

CONCLUSION
In this paper, a dc-dc converter with a large voltage gain was analyzed. The proposed converter consists of four switches, two inductors, and a capacitor. The voltage gain of the proposed converter in step-up mode is more proper than the conventional method. Besides, the input current is divided into the inductors and it causes the efficiency to be high. The steady-state analysis of the proposed converter was discussed thoroughly in this paper. The efficiency of the proposed converter and also the stresses on the converter’s devices were compared in this paper.
