how to connect sum block in Simulink to both ideal switches

how to connect sum block in Simulink to both ideal switches as shown in figure

Hello Emad,

This ideal switch belongs to the Specialized Power Systems library. Terminals 1 and 2 cannot be connected to the signal ports. You should find power components/parts for those terminals like this:

For your model, probably this is what you need to do:

Good Luck

Hello Emad,

the issue here is that there are two types of wires that you are using. One is a standard simulink wire, which has the arrows indiciating flow of data. however, the other connections you are trying to use are actual electrical connections. These were designed so that you could build an actual circuit, that interacts with the more logical and math based simulink models. If you want to bring a signal from simulink into your circuit with a sum block, I would recommend using a controlled voltage source. https://www.mathworks.com/help/physmod/sps/powersys/ref/controlledvoltagesource.html

In the matlab control panel, you could type this: power_controlvolt

in order to open an example of how to use this type of block.
