  • Electric Vehicles in Smart Grids

    Plug in Electric Vehicles (PEVs) use energy storages usually in the form of battery banks that are designed to be recharged using utility grid power. One category of PEVs are Electric Vehicles (EVs) without an Internal-Combustion (IC) engine where the energy stored in the battery bank is the only source of power to drive the vehicle. These are also referred to as Battery Electric Vehicles (BEVs). The second category of PEVs, which is more commercialized than the EVs, is the Plug in Hybrid Electric Vehicles (PHEVs) where the role of energy storage is to supplement the power produced by the IC engine.

  • 三菱第五代IGBT应用手册

    三菱电机功率器件在工业、电气化铁道、办公自动化、家电产品等多种领域的电力变换及电动机控制中得到广泛应用。为了真正满足市场对装置噪音低、效率高、体积小、重量轻、精度高、功能强、容量大的要求,三菱电机积极致力于新型器件的研究、开发,为人类的节能和环保不断努力。第5代IGBT和IPM模块均采用三菱电机第5代IGBT硅片CSTBTIM技术,并具有正温度系数特征,与传统的沟槽型构造IGBT相比,降低了集电极一发射极间饱和电压,从而实现了更低损耗。同时改进了封装技术,大大减小了模块内部分布电感。本应用手册的出版,旨在帮助用户了解第5代IGBT和IPM模块的特性和工作原理,更加方便的使用三菱电机的半导体产品。三菱电机谨向所有购买和支持三菱半导体产品的用户表示诚挚的感谢。1.IGBT模块的一般认识1.1 NF系列IGBT模块的特点NF系列IGBT模块主要具有以下两大特点:1,采用第5代IGBT硅片在沟槽型IGBT的基础上增加电荷蓄积层的新结构(CSTBT)改善了关断损耗(Eoff)和集电极-发射极问饱和电压VEisat的折衷。插入式组合元胞(PCM)的使用增强了短路承受能力(SCSOA)并降低了栅极电容,从而降低驱动功率。CSTBT:Carrier Stored Trench-Gate Bipolar Transistor载流子存储式沟槽硼型双极晶体臂
