Pspice电路仿真中变压器模型的使用

详细阐述了Pspice电路仿真中变压器模型的使用方法和注意事项,包括通用线性变压器模型、由线性磁心模型构成的线性变压器模型、具有磁滞现象和饱和特性的非线性磁心构成的非线性变压器模型.还介绍了利用电压控制电压源和电流控制电流源构成的具有交流和直流传输特性的理想变压模型.另外,提出了利用模型编辑器建立非线性磁心模型的两种方法:参数提取法和试错法,并且设计了测试电路对磁心模型进行测试.

Using Methods of Transformer in Pspice

Using methods and consideration of transformer model in Pspice simulation is outlined in details,including linear transformer and core model,nonlinear transformer and core model with hysteresis and saturation. Otherwise,introducing ideal transformer constituted of VCVS (voltage control voltage source) and CCCS (current control current source). In addition,presenting two ways for creating nonlinear core model using Model Editor,Parameters Extract and Trial and Error,and designing circuit to test core models.
