How do I find which blocks are used in this scheme?

I am new to Matlab's SIMULINK, and my next assignment includes modelling and simulating a PV Module.

I'm having a problem finding which blocks are depicted in the scheme though, and I've tried looking over the entire library to find them by their pictures with no avail.

I can so far tell the square blocks are simple mathematical operators, but what about the one with an arrow enclosed in a circle (Ipv) and the pentagonal ones ([Im], [V])?

Any help would be appreciated. Thank you.

Hi Mone,

I asssume you want to know the blocks used in the simulink model.

As per my knowledge the "pentagonal ones ([Im], [V])" are "From" blocks and "Goto" blocks which you can find by their respective names. Here is a documentation link to know more about them:

Accept input from Goto block - Simulink (mathworks.com)

"the one with an arrow enclosed in a circle (Ipv)" is the "Controlled Current Source " block. To know more about it you can refer to the following link

Implement controlled current source - Simulink (mathworks.com)

The square blocks written "v" and "i' inside them are voltage measurement block and current measurement blocks respectively.

Measure current in circuit - Simulink (mathworks.com)

Measure voltage in circuit - Simulink (mathworks.com)

In order to find these blocks inside simulink library use the library address given in the documentation. For exapmple:

I hope this answers your question.

Tushar,

This has been of great help. Thank you.

Good luck to your future endeavours,

Mone.

Tushar,

Sorry for bothering you with newbie questions, but I have another block that I'm finding a hard time identifying.

Is this the standard Math Function power block, just labeled differently?

Thank you in advance.

Hi @Mone

I understand that you are not able to find which block depicts which component.To find more about the component

one workaround is to double-click the block so that you will get either a description page or parameter page which will have a detailed description about the component.For example if I double-click on inport component,the following is its component page.

I hope this resolves your query.

Thanks,
