DC TO DC CONVERTERS AND ITS APPLICATION FOR RAILWAY SYSTEM- A REVIEW

In modern technologically advanced world, power electronic based converters are extensively used. Among them DC to DC converters are majorly used in transportation system because of its increased efficiency and regenerative system. The railway traction system is eco-friendly, pollution free and largely used transportation system in the world. A review of different types of DC-DC converter, isolated, nonisolated and its recent application in railway traction system is presented here. This paper also covers its key features such as high voltage conversion ratio, ripple factor, galvanic isolation and efficiency performance of DC to DC converters.
