Doubt in Ideal Switch

In Ideal Switch, if g=0 the switch are closed and if g=1 are open, sure?

Answer 1

[Arnaud Miege]

Are you referring to the Ideal Switch from SimPowerSystems? If so, look at the documentation:

"The Ideal Switch block is fully controlled by the gate signal (g > 0 or g = 0). It has the following characteristics:

• Blocks any forward or reverse applied voltage with 0 current flow when g = 0
• Conducts any bidirectional current with quasi-zero voltage drop when g > 0
• Switches instantaneously between on and off states when triggered"

HTH,

Hello, I tried using the "ideal Switch" block in Simpowersystems. I conneceted it to a battery I coded a matlab function block with if commands to give instructions to the switch via the gate(which is a simulink in put signal) to toggel between off and on. But it does not work.

so see what I did.

in the matlab function block

i did if command as follows,

if u==1 y=0; else y=1; end

but when i pass "1" through it still outputs the voltage in the battery. I have the voltage measurement between the switch and the negative port of the battery. so I have a display attached to the voltage measurement.

Please assist me with this issue.

thanks.
