DS5381 Low-Voltage Electronic Load Unit (60 V)

适用于电机PHIL仿真的低压电子负载单元

dSPACE的DS5381 Low-Voltage Electronic Load Unit能够对硬件在环（HIL）仿真的电机和发电机电流进行模拟。由于电压范围高达60V，因此该模块十分适合要求48V以上板载车辆电压的应用。

  • 非常适合三相电机应用

  • 每个模块100 A, 通过并联操作达到更高电流

  • 利用基于 FPGA 的电机仿真进行操作

只需要一个负载单元即可模拟三相电机。典型的测试应用领域包括电动转向系统、起动器与发电机系统以及轻度混合驱动。

主要优点

DS5381 Low-Voltage Electronic Load Unit使用与被测设备 (比如：ECU) 相同的电源电压。因此，在ECU和DS5381 Low-Voltage Electronic Load Unit之间循环的有效功率比直流供电单元的实际功率要高得多。这种能量回收显著提高了整个系统的能源效率。为了提高整个系统的功率，多个负载可以并联运行以获得更高的电流。
