【摘要】 近年来,由于化石燃料的日益紧缺以及自然环境的不断恶化,电动汽车受到了人们的广泛关注。然而,其发展和商业化进程受到了诸如价格高昂、电池组庞大笨重、续航里程短、充电时间长以及充电频繁等因素的严重阻碍。为了解决上述问题,人们提出了基于感应电能传输技术的路面供电电动汽车(或称为在线电动汽车)。本文从供电导轨和拾取机构、谐振变换器和控制策略、电磁屏蔽技术等几个方面综述了感应电能传输系统在路面供电电动汽车领域的应用现状。此外,并就应用于路面供电电动汽车感应电能传输系统未来可能的发展趋势做了探讨。更多还原

【Abstract】 In recent years,electric vehicles(EVs) are widely concerned due to fossil fuel shortage and environmental deterioration.However,their development and commercialization are obstructed by significant drawbacks,such as the high price,overweight of battery pack,short driving distance,long charging time and frequent charging requirement,etc.To solve these problems,the so-called roadway powered electric vehicles(RPEVs) or online electric vehicles(OLEVs) using an inductive power transfer(IPT) technique have been proposed.This paper presents the recent research advancements of IPT systems for RPEVs(IPTS-RPEVs) application,including the power track and pick-up,resonant converter and control strategy,and electromagnetic field shielding methods.Moreover,the possible future trends of IPTS-RPEVs are also been discussed.更多还原
