老师你好，我刚学simulink建模，但是下图的很多模块都找不到，老师能帮我下吗

Constant -Simulink/Commonly Used Block /Constant
PV array (这个模块你可以上网找，有的)
Powergui –SimPowerSystem/Powergui
CSS- SimPowerSystem/ElectricalSources/Controlled Current Source
CM-SimPowerSystem/Measurement/CurrentMeasurement
VM-SimPowerSystem/Measurement/VoltageMeasurement
Scope-Simulink/CommonlyUsed Block /Scope
Product-Simulink/CommonlyUsed Block /Product
Display-Simulink/Sinks/Display
RL-SimPowerSystems/Elements/SeriesRLC Load (然后打开，选择时RL)
PWM,MFPT,Boost是你自己定义，根据它们的功能而写，从Simulink/User-Defined Fucntion/ Embedded MatlabFunction

其实我不是老师，我只是越南学生在中国读书。我也不太会的。
