How can I connect my mosfet switch to the rest of the circuit?

Be mercyful, this is the first time I ask a question.

I need to use simulink to simulate the behaviour of a boost converter (BC). I am trying to create my circuit layout but I am not able to connect the Mosfet Switch Block and the Voltage Measurement Block to the rest of the circuits.

I have tried everything and looked everywhere but wasn't successful. I am aware of the incompatibility between simscape and simulink blocks but all my blocks come simscape-electrical with the exception of the pulse generator (which i weirdly was able to connect). I alos would like to know why i had to use the 'powergui' block is configure all the other blocks.

You are trying to connect blocks from the Specialized Power Systems library with the Simscape Electrical library. They dont mix. Confine yourself to the one or the other. The powergui block is a requisite for using blocks inside the Specialized Power Systems library.

I would advise to not use blocks from the Specialized Power Systems section.

Thank you for your answer. How can i confine myself from using certain components if I need them for the circuit? Can i find all of my components within the same library i.e either the Simscape Electrical library or the Specialized Power Systems?

The Simscape Electrical library indeed has a very broad selection of components and should be sufficient for most simulation works. The MOSFET block you are using from the Specialized Power Systems library has an equivalent in the Simscape Electrical library: https://nl.mathworks.com/help/physmod/sps/semiconductors.html

In the older days, only the Specialized Power Systems library was available. So today, I see it more as a legacy library for people still wanting to use it for their old models.

I understand this. However not all the components I need are within the same library. For example, I was able to find an alternative to the voltage measurement block found within the Specialized Power Systems library using the voltage sensor block in the Simscape Electrical library. However, this is not the case for all blocks

As displayed by the picture of my circuit above, I need to connect my circuit to the scope and display blocks that come from the simulink library but I am not able to do so. I have also tried using a PS-simulink converter but that does not help. Here is an updated screenshot of my circuit (just changed on connection).

You have that Voltage Measurement block connected across the resistor to measure the voltage.

I wonder what that third connection point to the Voltage Measurement block would do?
