how to simulate buck,boost and buckboos converter

[neerza]

has anydone tried simulating this circuit?i need some pointers..

Hi neerza,

What, exactly, are you trying to do?  What is your application?  What software are you using?  (If LabVIEW, what version and with what toolkits/modules?)

If you are simply trying to simulate a circuit, you may want to take a look at NI Multisim.

dear sir.i'm using labview 7.1.its basic packages.my lecturer said that i need to build the simulation using functions available in labview.using equations to produce waveforms of the converters but i have no idea in doing that.

Hi neerza,

It sounds like you know what you want to do, you just need to learn some LabVIEW fundamentals.

I recommend you look at the six hour tutorial for LabVIEW .  Also, I think a MathScript node may be a good choice for coding an algorithm to perform this kind of simulation.

[neerza]

sir,what is mathscript?i dont know bcoz its not in my sylibus.it is the same with matlab?

Mathscript is similar to Matlab. in that you can directly type some valid algorithm inside the Mathscript node, that ll get executed as per it.

It is integrated inside LV itself.

But, I think, it is available only from LabVIEW 8.x & above...

[Eriquito]

parthabe is correct;  I'm sorry I forgot you were using an earlier version of LabVIEW.

You will need to implement your logic in the LabVIEW block diagram yourself;  you do have the much more limited Formula Node available to you in LabVIEW 7.

[neerza]

means that i need to use the formula node to simulate the circuits of the converters is it?

[parthabe]

Yes.
