How to create pulsed DC?

Howdy Y'all,

Take a look at this.

I built this circuit to pulse one of my transformers.  It's a neat little circuit and may be good for an HHO application...

It is excellent for hydrogen. It is also very good to drive different magnetic motors. And the best, it is cheap. They need a few small gut mods for the production of hydrogen.

Take care,

AC and DC are different stuff.

For example Ac got frequency. How you will increase frequency ?

U need to get familiar with basic electronics. Power supplies and so on .

Simplest way to get pulses out of AC is to smooth it to DC. Full bridge (diodes) and some smoothing elements like parallel capacitor (not effective)

Howdy Y'all,

That circuit I posted isn't really AC.  You get transformed square wave DC pulses out.  The description of the circuit is not very good, and the circuit doesn't generate a sine wave so the circuit is not very effective as a inverter, but it can give you alternating DC pulses.  I built it and looked at the waveform with my oscilloscope.

I tired to rectify AC into two channels of pulsed DC with poor results, I'm using the IN400x series of 1 amp rectifier diodes.  Can someone explain what diodes would best serve the purpose for rectifying ac signals from an audio amplifier?

What I did in my experiment was split an AC to DC rectification circuit which uses 4 diodes straight down the middle with diodes on the left in their normal positions and diodes on the right in the same clockwise positions as the ones on the left - I used pulsed DC from each half of the sine wave...

My primary concern is the type of diode to be used.  The setup did produce bubbles, but not very many - apparently, when I set it up, the diodes all had different properties. The diagram below shows basically what I did... Red dots indicate the electrodes, purple indicates the AC source, black lines are the circuit and the green arrows indicate the basic direction of flow.
