If you resonate the piezo element - it will draw peak current.Hello, I am so glad that you decided to help me out with this.
Well how much current is not really matter to me. It can mr from 1mA to max of 555 output 200mA. Because the load is piezo material. So only thing I need is suply my piezo with 400-450V @ 25-30kHz.
I see you suggest me the power mosfet. Will that need transformer for specified output or?
And could I use the backwards transformer?
I already tryed backward with simple circuit but the voltage just jumps up and drop around 120 to 500V. If i only could stabilze that.
If you don't resonate the piezo - the whole exercise is pointless.
