Abstract
This paper proposes a design and implementation of the bi-directional DC-DC converter for Wind Energy Conversion System. The proposed project consists of boost DC/DC converter, bi-directional DC/DC converter (BDC), permanent magnet DC generator and batteries. A DC-DC boost converter is interface with proposed wind system to step up the initial generator voltage and maintain constant output voltage. The fluctuation nature of wind makes them unsuitable for standalone operation. To overcome the drawbacks an energy storage device is used in the proposed system to compensate the fluctuations and to maintain a smooth and continuous power flow in all operating modes to load. Bi-directional DC-DC converter (BDC) is capable of transforming energy between two DC buses. It can operate as a boost converter which supplies energy to the load when the wind generator output power is greater than the required load power. It also operates in buck mode which charges from DC bus when output power is less than the required load power. The proposed converter reduces the component losses and increases the performance of the overall system. The complete system is implemented in MATLAB/SIMULINK and verified with hardware.

Summary
The growth in the global energy consumption is predicted to be 1.6% - 1.7% per year. The global consumption is going to hit 28 TW by the year 2050. As the demand for energy is rising day by day, most of the global power demand is supplied by burning. Coal power plants contribute 59% of total sulphur dioxide pollution and 18% total nitrous oxide per year. 15% of the coal is converted as electrical energy. For producing 1 unit of power, total carbon emitted is 0.8 Kg. Renewable energy is emerging energy production system which produces eco-friendly, pollution free energy from the natural sources like sunlight, wind, geothermal, tidal etc. Renewable energy will contribute the global effort to meet the challenges of climatic changes by providing clean energy [1]
