Hello everybody...

I am working on some project were piezo crystal needs to oscillate to 30KHz..
I set up the 555 chip in astable mode to work on 30KHz, but I don't have enough current..

So main question is: How can I get the 100W on the output of 555 chip with the 10-16V.

I mean how can I get high current of 5-10Amps with specified voltage...
Can someone provide me some circuit and components that I need to use...

If you need any detailed info about this, fell free to ask.. I will provide any info needed...

Andy help is appreciated.
Thanks!

 

What are you trying to do? There maybe a much easier way.

 

I am trying to make piezo crystal to oscillate at 30KHz with the 100W power at 10-15V...

 

where did you get piezo crystal rated for 100W? what is the part number?

 

It's not really rated crystal.. But it can handle 100Watts... It's a tape shape piezo...
If i put the piezo only on the 555 output on the frequency I can hear lets say 5Hz..
I hear the piezo ticking...

Of course I can't hear it on the freq above 20KHz but 555 timer sends those pulses, know I just need to amplify them...

 

Is the natural resonance of the piezo supposed to set the frequency? If so, then the 555 is redundant. What you need is a power oscillator like is used in an ultrasonic cleaner.

 

The 555 timer is in astable and he sending the output pulses to the piezo.
Now I just need to give him more current.

Unless I am missing something here?
I don't know does he have some sort of natural frequency, do You have any schematic of that power oscillator?

I attached pic... My piezo is simmilar to this one.

 

My piezo is simmilar to this one.

Which will take 5W forever, or take 100W for about 1 millisec.

 

Well according to information I have. Piezo takes 8W for cm^2.
My piezo dimensions are:

1.4 x 8.5 = 11.9 cm^2
8W x 11.9 cm^2 = 95.2W

Unless my info are not correct???

So are you telling me that if I put my piezo at 30KHz with 5W and put the drop of water on it, I will see the power of 30KHz??

 

post the datasheet or manufacture/part number of this piezo

 

I have the same felling as MikeML, it seems look not that much watts, if you want to see the 100 Watts is here.

 

I checked part num. on my piezo and I didnt get any results on Google. Part number is: 20H14-015D

Informations I have for power dosen't have to be true....so if anyone has more reliable please post them.
