DS5386 High-Voltage Electronic Load Module

用于功率硬件在环仿真的电子负载（1,250 V）

dSPACEDS5386 High-Voltage Electronic Load Module可以在硬件在环（HIL）仿真中模拟电机、电池和电网。因此，我们能够对电压高达1250 V、功率数兆瓦的电力电子控制单元进行测试。

  • 针对不同应用程序和特殊拓扑的紧凑模块化硬件
  • 模块可以并联连接以提高功率输出。
  • 基于碳化硅（SiC）技术

该领域最常见的用例之一是逆变器测试, 其可用于汽车牵引电机、工业传动装置和零排放飞机。然而，高度灵活的电子负载也可以模拟任意的交流和直流电源，它可以作为电网在陆地、空中和海上运行，同时它也可以作为电池模拟器。DS5386 High-Voltage Electronic Load Module可以集成到dSPACE模拟器机柜中，作为功率HIL测试系统。这些系统专为功率级的HIL仿真而设计，弥补了信号HIL仿真测试与测功机或原型车辆测试之间的差距。

主要优点

  • 基于尖端的多级硬件架构和获得专利的基于观测器的模型预测电流控制（MPC），我们成功实现了顺畅、准连续的电流表示。
  • 低延迟模型接口能够对高达数kHz的电气频率进行基于电流的模拟
  • 使用相同模块进行供电和负荷模拟的扩展
  • 对于空间要求很低的组装件进行高能量密度的紧凑设计
  • 方便用户使用的水冷电力电子设备
  • 由于主电源没有能量回收，循环能量流实现高效操作（由于能量回收，仅需15%的仿真功率进行供电）。

Thanks to the modular approach of the dSPACE power HIL test systems, they can be easily adapted to a wide range of applications and individual power ranges. For this purpose, the systems are configured with the required number of DS5386 High-Voltage Electronic Load Modules.

The configurations indicated here are the minimum configurations that can be installed in one emulator cabinet. It is possible to connect several modules or even several cabinets in parallel to achieve higher power outputs. Thus, any system in the voltage range between 0 and 1,000 V and in the power range from a few kW up to several MW can be set up.
