What is the value of C1? is it 1.5nF (1500pF)? I doubt that it is 152 Farads.
You need to be consistent with your units.
Back to basics: The transistor has no source of base current, so the circuit shouldn't oscillate. Arvinfx, are you sure there is no resistor anywhere in the circuit? If not, perhaps it is in the transducer. Did you buy this, or remove it from some other product? Can you give us a part number?
Ah, 2 Megohms. I missed that.Ron, read aRVINFX's replies to all the questions I put to him...
I need to see how the base of the transistor can feed the piezo transducer with 45W!
Here are the results of my simulation. If anyone wants to run it, I'll zip all the required files and post it.
Here is a zip of all the files needed (I think) to run the sim.This is that what I want! please share it
And what is the simulator program's name?
Here is the 1N753 model.Thanks Roff.
But when I run the Pspice simulator it gave me two errors one of them is for bu406 and other one is for 1n753.
What should I do?
.model 1N753 D(IS=1E-11 RS=4.685 N=1.27 TT=5E-8 CJO=3.463E-10 VJ=0.75 M=0.33 BV=6.106 IBV=0.01 )
Here is the 1N753 model.
In my circuit, the BU406 model is already in BU406bd.asc, which gets called by the top level sim, piezo oscillator.asc. Why do you need the model? Are you trying to run the sim with the standard BU406 model? You can do that, but the results will be meaningless, because the model does not include the Veb breakdown.
