Abstract:

Today, increasing importance of energy and production costs have led researchers to work in these areas. In addition, the formation of a cleaner environmental awareness and the overall consumption of renewable energy sources, such as the rapid increase in the rate of spread of the reasons is caused almost every area of power electronics. Thus, distributed power generation systems have increased the importance of power electronics and energy storage issues. After a while of fossil fuels not to meet that need and the increasing costs have led to research and development in the concept of electric vehicles for the transportation field. In this study, how the development of electric vehicle technology, provide up to the present time, evolving and changing with the development of electric vehicle technology types examined. Electrical energy consumed in the propulsion system of electric vehicles, fuel cells, or the provision of power supply in the event of a major problem, short or long term storage of electrical energy is emerging as a difficulty. Storage elements which many regard as the high cost and technological properties are not sufficient. In order to minimize this problem, re-sources of energy lost during braking, the transfer has been accepted as a correct approach. By the usage of bi-directional DC-DC converter, the efficiency is increased, the dimensions are reduced and the braking energy is transferred back to the source. In this study, the converter has been tested on a DC motor drive.
