混合动力永磁同步电机驱动试验装置

开放模式

本例展示了用于典型混合动力汽车的永磁同步电机(PMSM)驱动器的测试线束。测试线束可用于确定在给定速度和扭矩下运行时的总体驱动损失。Simscape™electric™Motor & Drive (System Level)模块可以使用该测试束的表状损失信息，快速模拟完整的驱动周期，同时准确预测整体系统效率。

下面的第一个图显示了频谱分析仪的结果。第二个图显示测量和命令转子速度。绕组电流也被绘制出来，这解释了电机转速中的高频纹波。

下表显示了ee_pmsm_drive模型中各个组件的功耗。这些总数是使用记录的Simscape变量和损失计算实用程序ee_getPowerLossSummary从模拟结果中计算出来的。显示了负载的总输出功率以及损耗。

运行PMSM Drive Test Harness模型生成仿真数据，当转速= 1400rpm，扭矩= 200Nm时，效率= 85.9703%，按组件计算的瓦数损失如下:FEM_Parameterized_PMSM'} 3610.2 {'ee_motor_pmsm_drive. three_phase_inverer . switch2。IGBT'} 158.7 {'ee_motor_pmsm_drive.Three_Phase_Inverter.Switch3。IGBT'} 157.3 {'ee_motor_pmsm_drive. three_phase_inverver . switch5。IGBT'} 155.3 {'ee_motor_pmsm_drive. three_phase_invertor . switch6。IGBT'} 153.4 {'ee_motor_pmsm_drive. three_phase_invertor . switch4。IGBT'} 151.4 {'ee_motor_pmsm_drive.Three_Phase_Inverter.Switch1。IGBT'} 143.6 {'ee_motor_pmsm_drive. three_phase_逆变器。D2'} 23.5 {'ee_motor_pmsm_drive. three_phase_逆变器。D1'} 21.6 {'ee_motor_pmsm_drive. three_phase_逆变器。D4'} 21.4 {'ee_motor_pmsm_drive. three_phase_逆变器。D6'} 20.7 {'ee_motor_pmsm_drive. three_phase_逆变器。D5'} 20.4 {'ee_motor_pmsm_drive. three_phase_逆变器。D3'} 19.5 {'ee_motor_pmsm_drive. three_phase_逆变器。C0'} 11.2 {'ee_motor_pmsm_drive.
