精选示例
高压电池充放电
此示例展示了与混合动力电动汽车中所用高压电池类似的高压电池。该模型使用源自于动态驾驶循环的真实 DC 链路电流曲线。总仿真时间为 3600 秒。
IPMSM 外环控制器评估
此示例展示了如何控制基于内置式永磁同步电机 (IPMSM) 的电力牵引驱动装置中的转子角速度。为了评估外环速度控制器，内环电流控制器被替换为三相受控电流源。理想转矩源提供负载。Scopes 子系统包含示波器，可用于查看仿真结果。Control 子系统包括基于 PI 的外环控制器。在时长三秒的仿真过程中，角速度需求为 -1000 rpm、2000 rpm、3000 rpm、4000 rpm，然后是 5000 rpm。
Differential Pair Amplifier
A differential pair amplifier circuit. The circuit can be used to explore the properties of a differential pair amplifier. The model can be tested using differential and common-mode inputs. The balanced output has zero gain in common-mode provided that the two transistors have identical properties.
太阳能电池功率曲线
此示例展示了如何生成太阳能电池阵列的功率-电压曲线。理解功率-电压曲线对于逆变器设计至关重要。理想情况下，在给定辐照度水平和电池板温度下，太阳能电池阵列应始终以峰值功率运行。
反馈型线性电压调节器
此示例展示了由离散组件构造的简单电压调节器电路。波动电源建模为 20 V DC 电压加上 1 V 正弦变化。齐纳二极管 D1 将运算放大器的非反相输入设置为 3.2 V，因此，由于运算放大器的增益较大，其反相输入和输出也为 3.2 V。因此，调节器电压输出调节为 3.2*(1000+470)/470 = 10 V。使用 NPN 双极晶体管可以提供比典型运算放大器所能提供的电流更高的电流。该模型可用于检查电路运行，并支持选择组件以实现所需的电压调节。
