Certain investigations on Performance improvement of front End power factor correction Converter in electric vehicle Applications

Abstract

Electric Vehicles EVs are evolving fashion trends in automotive newlinecircles and consumer awareness about them is developing quickly Batteries newlineof diverse technologies are the main energy storage elements present in these newlinevehicles With the growth of EVs battery chargers for automotive newlineapplications fetch a large market for the power supply industries Batteries are newlineto be charged periodically from a single phase or a three phase supply which newlineis usually provided by the power grid newlineEVs are provided not only with a DCDC converter which provides newlinepower for the additional parts but also with an ACDC converter to supply newlineelectric power from the power grid to the high voltage battery Conversely the newlinevast usage of EVs will lead to several penalties to the power grid, mostly the newlineload management becomes difficult and the electrical power quality gets newlinedisturbed Consequently there is necessity to decrease the line current newlineharmonics demanding the need for Power Factor Correction PFC and newlineharmonic reducing circuits. Furthermore, for meeting the Power Factor PF newlineand regulatory standards for the AC supply mains PFC is indispensable newline newline
