I want to actuate the piezeoactuator which is taking more than 100vdc. But i have a sorce of less than 30vdc. Can any one tell me what to do.

Get another voltage source. Simple as that.

If the actuator will be used to position something and needs 100 V, then you will need a high voltage supply that powers an HV buffer.
If the actuator needs only a 100 V pulse, you could use a transformer or a Marx pulse multiplier.

For my Nixie lamp clock I made a boost converter that uses 12V as input and produces ~200V. Basically just a 555, a MOSFET, an inductor and a capacitor.

Welcome to PF. :smile:

Can you post a link to the datasheet for the actuator? That would help a lot. Thanks.

Can you share more information about how you converted 12v to 200v..
In my case i have to produce 200v from 28v source.

Without having a datasheet, and knowing the application of the piezoactuator, this thread is lost.

Use google, Luke.

I gave you several key words to search for, they should put you on the track. But, as others already suggested you more than once, choice of the converter depends on the power consumption of the actuator. No datasheet, no way to choose a fitting solution.

This is starting to sound more like your other thread (which is now closed):
I need to design a circuit which takes around 28V of input and outputs the 200v with 20A. Can any one help me.

You don't need that high of a power level to drive a piezo actuator. Last chance -- please link to the datasheet for the piezo actuator, and tell us your level of experience in working with high voltage electronics. Thank you.

I dont have any datsheets of piezeoactuator. All i know is i want high voltage to actuate it. And i want high current in beginning. Lets say less than 5ms i have to apply high current then i dont need high current. Since i am fresh to these power converting i dont have much knowledge about it. Can you please suggest anything

Where did you find the piezo-actuator?
What are its dimensions?
What do you intend to use it for?

If you read the little-biddy writing on the side of the piezo, what does it say? :wink:

Can you upload a picture of it? (use the "Attach files" link below the Edit box)

Without a datasheet, you do not know voltage and you do not know current. Without a datasheet, we do not know voltage or current, so we cannot help you. So I locked this thread. If you want the thread reopened send a PM to myself or @berkeman.
