Hello Titouan,
First, here are some links of training and examples that are useful:
If you need more info on simscape basics, look here: https://www.youtube.com/watch?v=fsTHCRtUNCA&t=1621s
And see this example: https://www.mathworks.com/help/physmod/simscape/examples/full-wave-bridge-rectifier.html
and see this example: https://www.mathworks.com/help/physmod/simscape/examples/operating-point-rlc-transient-response.html
Here is how to set up your circuit:
You can use this block to be switch K: https://www.mathworks.com/help/physmod/simscape/ref/switch.html
You will need to use a voltage sensor block to measure Vp: https://www.mathworks.com/help/physmod/simscape/ref/voltagesensor.html
if you use a converter block to bring this signal into simulink, and use an comparison logic to determine when your switch should turn on or off: https://www.mathworks.com/help/physmod/simscape/ref/pssimulinkconverter.html. You should add a simulink transfer function with a numerator of [1], and a denominator of [Ts 1] and pick a TS to create a low pass filter on your voltage input. Maybe start with 1000.
Then, make sure the simulink signal is larger than the switch threshold voltage, bring it back into simulink and use it to control that switch: https://www.mathworks.com/help/physmod/simscape/ref/simulinkpsconverter.html
