全球知名半导体制造商ROHM为即将参战于2017122日开幕的电动汽车全球顶级赛事FIA Formula E锦标赛2017-2018(第4 赛季)的文图瑞电动方程式车队(VENTURI Formula E Team)提供SiC”功率模块,助力赛车实现更高性能。

ROHM作为SiC功率元器件的领军企业,从第3赛季开始与文图瑞签署官方技术合作协议,为逆变器这一赛车核心驱动部件提供全球最先进的SiC功率元器件。

上个赛季仅提供了二极管(SiC-SBD),但从第4赛季开始,将提供集成了晶体管与二极管的SiC”功率模块,与未搭载SiC的第2赛季的逆变器相比,成功实现43%的小型化与6kg的轻量化。

今后,ROHM将继续为包括电动汽车领域在内的社会发展贡献力量,进一步推进功率半导体的技术革新。

 

<逆变器比较>


 

Formula E是于2014年由国际汽车联合会(FIA)主办的全电力驱动的汽车赛事,因其不使用化石燃料非常环保,所以在香港、柏林、纽约等全球多个城市的市中心举办了公路赛事。如何毫无浪费地充分利用电力是Formula E的制胜关键,其技术革新有望引领普通电动汽车的技术发展。另外,虽然是个创建不久的赛车运动,但世界各国的汽车相关企业已经参加进来,甚至包括日本在内的各大汽车制造商都纷纷宣布参战。

 

ROHM除了拥有丰富的电源IC和各种控制IC之外,还拥有强大的功率元器件、电流检测用分流电阻等分立产品阵容,多年来在汽车领域积累了丰硕业绩。其中,对于与传统Si(硅)功率元器件相比,在大幅降低损耗方面被寄予厚望的SiC功率元器件,ROHM也正在推进最尖端的开发,不断加速其在电动汽车(EV)的电机和逆变器中的应用。

 

 

<寄语>

文图瑞电动方程式车队首席技术官 Franck Baldet

Formula E是唯一能够在新一代电动汽车中尝试最尖端技术的赛车运动。对于在Formula E赛事中最关键的电力管理方面能够与ROHM达成技术合作伙伴关系,我们感到非常高兴。

在即将举办的第4赛季中,赛车采用ROHMSiC”功率模块,成功实现轻量且安装空间最小化的逆变器。通过应用最尖端技术,有望大大缩短单圈时间。未来,我们希望通过与ROHM的合作伙伴关系,继续推进技术革新。

 

ROHM Co., Ltd. 功率元器件生产本部 统括部长 伊野和英

多年来,ROHM一直为发展迅猛的汽车领域提供优质产品。目前,汽车领域被ROHM视为重要关注领域,特别是在近年来的混合动力车和电动汽车中,半导体元器件将会发挥越来越重要的作用。

此次为Formula E赛车提供的SiC功率元器件就是其中之一。在去年的第3赛季(2016-17赛季)中,仅提供了SiC SBD,今年则提供集成了SiC SBDSiC MOSFETSiC”功率模块,这将进一步提升赛车性能。今后,ROHM将继续助力包括电动汽车在内的众多行业及领域实现更高效的能源转换,为社会发展作出贡献。

 

<采用SiC的优势>

此次,文图瑞电动车队赛车逆变器所搭载的SiC”功率模块,采用了ROHM开发且独有的模块内部结构和优化了散热设计的新封装,成功提高了额定电流。另外,与普通的同等额定电流IGBT模块相比,开关损耗降低达75%(芯片温度150时),这将非常有助于应用的节能。不仅如此,高频驱动不仅可实现外围部件的小型化,在高频驱动时开关损耗的降低效果更显著,因此还有助于冷却系统等的小型化。

Formula E中,通过将此SiC”功率模块应用到逆变器这一赛车驱动的核心部件中,与搭载SiC前的第2赛季的逆变器相比,成功实现43%的小型化与6kg的轻量化。另外,与搭载了SiC-SBD的第3赛季逆变器相比,也成功实现了30%的小型化与4kg的轻量化。

 

 

<关于“Formula E”>

Formula E是主办顶级汽车赛事一级方程式世界锦标赛(F1世界拉力锦标赛(WRC等的国际汽车联合会(FIA)于2014年开始举办的电动汽车界全球首创的方程式赛车运动。作为电动汽车研究开发的试验场,旨在进一步促进并提高全社会对电动汽车的兴趣。

赛车全部由电力驱动,因此与使用燃油引擎等的现有赛车运动相比驱动噪音小,且行驶过程中不排放废气。也正是因为这一特点,比赛全部在城市公共道路上进行。第4赛季揭幕战将于201712月在香港举行,并计划在马拉喀什、圣地亚哥、墨西哥城、圣保罗、罗马、巴黎、柏林、苏黎世、纽约和蒙特利尔等共10个城市举办。

 

<关于“文图瑞电动方程式车队”>
