摘要
Multisim仿真软件中没有热敏电阻模型,通过应用Multisim 11.0元件库中的基本电阻元件结合热敏电阻的温度特性,介绍了设置PTC、NTC的仿真近似模型的方法,将该热敏电阻模型应用于小冰箱的制冷控制电路中,对其温控系统进行了相应的参数扫描仿真分析,实现了预期的温控功能,从而验证了该模型建立的正确性。
No thermistors model in Multisim simulation software, through application Mulrisim II COmponents library in the of basic resistance components combined thermistor of temperature characteristics, describes has set PTC and NTC of simulation approximate model of method, will the thermistor model should for small refrigerator of refrigeration control circuit in the, on its temperamre control system for has corresponding of parameter scan simulation analysis, achieved has expected of temperature control features , to validadon has the model established of correcmess.
