50 kW 至 350 kW 的充电器
用于超快速直流充电系统的高效设计系统
电动交通的前景是光明的。根据国际能源署（IEA）*的报告，2021 年第一季度电动汽车（EV）销量同比增加约140%。然而，要保持这一势头，关键是要让电动汽车用起来和传统汽车一样方便，而这正是大功率直流充电的用武之地。
鼓励人们将电动汽车作为主要交通工具，在很大程度上有赖于找到方法延长续航里程。尽管汽车制造商致力于开发更高效的电池，但同样重要的是打造强有力且方便易用的充电基础设施。这种对更远续航里程和更可靠基础设施的需求，就转变成了对尽快提供更多电力的更大需求。
借助高达350kW的大功率直流充电系统，续航200公里需要充电大约7分钟，刚好可以有时间在前往最终目的地的途中喝杯咖啡。使这些充电器快速、高效且易用的技术，将有助于免除人们的“续航里程焦虑”，进一步促进电动汽车在全球各地的广泛采用。

在选择理想的功率半导体时，了解充电系统功率水平十分重要。最终，合适产品的选择取决于此因素。功率范围高于 50 kW 的充电器通常使用英飞凌的 IGBT、CoolSiC™ MOSFET和二极管、功率模块（例如 CoolSiC™ Easy 模块、IGBT EconoPACK™和IGBT EconoDUAL™系列）构建。采用 50 至 100 kW 的充电模块，通过并联这些模块来构建功率范围高于 100 kW 的充电设备。
我们的高质量功率开关组合可与丰富的驱动器无缝配合使用。所有开关都需要驱动器，而所有驱动器都需要控制。这正是我们还为电动汽车快速充电设计提供合适的 EiceDRIVER™，以及XMC™和AURIX™微控制器的原因。对于变换器管理，我们的高精度无芯电流传感器可带来理想的解决方案，实现变换器控制和诊断。最后，我们的OPTIGA™产品系列可确保实现充电站的数据保护及安全。
技术趋势
高功率充电系统的目标是缩短充电时间，以使电动汽车达到能够与内燃机汽车相提并论的程度。有两种可能的充电基础设施架构：隔离初级交流侧或次级直流侧。
隔离初级交流侧
如果是充电停车场，实践证明 2 MW 至 3 MW 的整体功率设置可提供 6 到 8 个高功率充电站。电力来自高效的中压变压器，通常是 22 kV 至 500 V，以隔离系统交流侧。接下来是交流到直流级，其中可能涉及也可能不涉及有源整流器。多脉冲无源整流是一种选项，使电流谐波符合现有标准。隔离初级侧可以让设计师自由地将非隔离直流-直流转换器拓扑用于直流-直流转换级。通常，多相降压转换器适用于此架构，带有直流转换模块。
隔离次级直流侧
第二个基础设施架构通过并联 50 kW 或 100 kW 充电模块达到 350 kW，适用于独立应用。

交流-直流系统在 EMI 滤波器后面，将交流电压转换为直流电压，通常配有可控整流器。直流-直流转换级通常为隔离型：首先将直流电压转换为高频交流电压，然后在变压器的次级侧再次转换该高频交流到直流电压整流。
这种功率类别采用的常见策略是使用功率模块而非分立器件。基于 IGBT 的解决方案采用 EconoPACK™和EconoDUAL™，适用于 Vienna 整流器和 AFE 以及交流-直流转换，通常在约 20 kHz 下运行。CoolSiC™ Easy 模块可使交流-直流转换器级在约 40 kHz 至 50 kHz 下运行。CoolSiC™也是直流-直流级的首选器件，可提高开关频率，从而减小整体系统尺寸并实现更高效率。
