高管访谈：通过高压IGBT、线性MOSFET等功率器件，Littelfuse赋能医疗设备创新
随着远程医疗、智慧医疗、数字医疗等创新概念的兴起，全球医疗电子产业发展换挡提速，未来几年将保持蓬勃发展的态势。在PCIM Asia 2023上，LITTELFUSE半导体应用技术经理刘鹏援引市场分析机构Statista的数据称，预计到2030年全球市场中美国、中国、法国和德国医疗设备市场规模均将超过500亿美元，其中美国医疗设备市场规模届时将超过2000亿美元。

他指出，针对医疗设备市场，Littelfuse提供三大产品线，分别是来自IXYS的功率半导体产品，包括可控硅、Mosfet、IGBT、二极管、三极管和驱动器等；来自Littelfuse的电路保护器件，包括保险丝、TVS二极管、保护IC等；还有来自C&K的按键产品，包括触控按键、按键开关和滑动按键等。
Littelfuse将医疗设备市场分为三个方向，分别是生命力支持设备、外科手术设备、诊断和治疗设备。
除颤仪AED属于生命力支持设备。刘鹏介绍称，围绕除颤仪，Littelfuse在电源系统、电池管理单元、开关按钮、用户界面和高压脉冲放电H桥(H-Bridge)等方面都有产品供应。在H桥应用上，Littelfuse提供独有的3000V IGBT，不仅提高了AED的可靠性，并且缩小了设备体积和设计周期。
除颤仪电路框图
应用于除颤仪的IGBT并非普通的IGBT产品，而是高压IGBT，器件的工作电压达到3000V。Littelfuse的Very High Voltage系列BiMOSFET兼具MOSFET和IGBT的优势，工作电压为2500V-3600V。除颤仪的电池电压一般为12V或24V，然后升压到2000VDC，H桥是目前除颤仪中主流的电路架构。根据刘鹏的介绍，现阶段在医疗设备用的3000V IGBT市场只有Littelfuse独家供应，是一个出货量很大的产品类别。除了IGBT，高压可控硅也是Littelfuse在除颤仪市场非常具有统治力的一个器件，在2500V高压可控硅市场几乎没有竞争对手。
他指出，过去几年，除颤仪设备在国内市场快速起量，原因在于政府政策对于公众健康更加重视，像体育场、学校、交通枢纽和医院等公共场所都开始要求配备除颤仪。未来，家用除颤仪是一个巨大的待开发市场，出货量可能远超过现有的市场规模。除颤仪也是本次Littelfuse在PCIM Asia 2023上重点展示的医疗设备方案。
X光影像系统DR属于诊断和治疗设备，Littelfuse在高压发生器、辅助电源和用户界面方面能够提供相关器件。
X光影像系统电路框图
刘鹏谈到，X光影像系统里面的高压发生器会产生一个150kV的高压，功率可能达到40-80kW的级别，Littelfuse高性能大电流的保险丝在其中起到了保护作用。另外，设备前端会用到Littelfuse的三相整流桥，850V-1000V的MOSFET应用在高压发生器(HV Generator)，高压的MOSFET是Littelfuse的强项，这些器件拥有超低的RDS（ON）和Qg，以及卓越的dv/dt性能，可以显着提高医疗产品的可靠性。
超声手术刀是一种外科手术设备，主要用于生物组织的切割与血管闭合等操作。在相关设备的AD/DC系统、电源系统和换能器等方面，Littelfuse提供了对应的解决方案。
刘鹏表示，超声手术刀电路的电路较为复杂。功放电路(Power Amplifier), 发出纯正的正弦波，推动换能器工作。由于换能器核心部件是压电陶瓷，在正弦波的激励下，换能器不停地震荡，将电能转化成机械能，会以55.5kHz的高频来进行切割。

在超声手术刀应用中，如果用方波驱动换能器，那么就会造成换能器异常损坏，因此纯正的正弦波才能保证换能器的工作寿命。Littelfuse提供极具创新价值的线性MOSFET管，可以承受严苛的正弦波驱动。
Littelfuse的技术创新在于，将MOSFET中间区域MOSFET晶胞的Vgsth人为调高，这是一个非常领先的工艺调整。当MOSFET 工作在线性区，大电流进入Littelfuse的线性MOSFET管时，器件表面的温度就会趋向均匀，不会因为热集中效应而失效。
除了这些典型的案例，刘鹏还向电子发烧友网记者介绍了Littelfuse 产品在创新医疗中的应用。比如：脉冲电场消融、血管内脉冲除钙化和呼吸机等方面的应用，涉及了4500V超高压IGBT等功率器件以及C&K的高性能开关，体现了Littelfuse在医疗电子领域的布局广度和布局深度。

【应用】大功率TVS二极管实现VFDs/IGBT逆变器差动保护
在几乎所有的工业控制系统中，变频驱动器(VFDs)/逆变器通常安装在电机的前端，以调节速度和节约能源。由于变频器/逆变器是提供电力的关键部件，因此其运行、性能和可靠性对于保持不间断的供电是至关重要的。本文着重介绍了力特（littelfuse）的TVS二极管和MOV在IGBT保护中的应用。
采用TO-247封装的MOSFET分立器件、IGBT分立器件、晶闸管和二极管增加了新的制造地点（LFPCNUSA2022-002）
描述- Littelfuse公司发布产品变更通知，宣布将部分MOSFET、IGBT、晶闸管和二极管产品的TO-247封装的生产地点新增至中国。此次变更不影响产品功能，但可能影响产品标记、BOM和标签等细节。受影响的产品清单见附录B，具体变更细节见附录A。

【应用】光耦OR-MOC3063S配合功率双向可控硅MAC4DSN用于控制电动调节阀24V交流电机电源
笔者最近在做热力管网中的电动平衡调节，电动调节的核心是电动调节阀。由于方案的尺寸限制，控制电动调节阀交流24V电源的方式选择了光耦+可控硅。可控硅按照AC220V的标准进行的选择，而光耦则需要有过零检测功能。据此笔者选择了奥伦德的光耦OR-MOC3063S搭配力特的功率双向可控硅MAC4DSN
逆天！我国电动车电池电压为何能比国际高一倍？
