Title: The best way
Post by: nucleopolymere on December 11, 2016, 06:22:00 pm

Hi guys ,
 I am in my first year of electrical engineering now and  I wanted to know what is the best way to build a high power signal generator like something aroung 30 to 50 khz and it could deliver around 100 W, Its is for building a ultrasonic cleaner with 2 50 W transducers. I just want the name of the circuit(s) so i can do my researches.

Thanks

For the power stage, LM3886 could be a choice.
An oscillator for a signal source shouldn't be a problem to find.

There is no name of the circuit, you're asking for a very complex system.

Many parts are needed to deliver high powers to transducers.
