In the current world scenario of increasing environmental issues and oil prices, development of Electric Vehicles (EV) have gained considerable importance and attention. Electrifying the conventional transportation system can reduce the use of depleting fossil fuels and can lead to better performance and reduced pollution. Power electronics will play a key role in making highly efficient electric vehicles which are low in emissions and having better fuel economy. This paper presents a review of the stateof- the-art power electronics technology in electric vehicles in detail focusing both semi-conductor devices as well as material technology. Also it discusses about the various power electronics systems placed in an electric vehicle. The paper concludes with a discussion of expected future trends in power electronics technology that will improve the markets for electric vehicles in coming years.Keywords

In a high - or medium-voltage substation, the operation of circuit breakers can induce high-frequency over voltages in low-voltage circuits known as an electromagnetic interference (EMI). The radiated and/or conducted EMI can be the cause of damage or malfunction of low- voltage electronic equipment. This paper focuses on the effects of EMI produced due to switching of medium vacuum circuit breakers (MVCB) on the functioning of numerical relays and measuring devices which are in the vicinity of 6.6 kV Vacuum circuit breaker and remedy for reduction of effects of EMI. In this paper, a unique and cost - effective solution has been suggested and implemented to bring down the EMI effects by installation of ferrite core on control cable bunch and effective galvanized iron (GI) sheet shielding between source (MVCB) and victim (numerical relay and meter).Keywords
