Title: How to Modify output Frequency of a Husky 400 Watt Inverter
Post by: Login to see usernames on May 06, 2009, 22:38:07 pm
This new topic is to attempt to adjust the output freq on a Husky 400 watt inverter.

I want to Thank Komatek for supplying the inverter.

Nice work, Electrojolt.

Thats a nice way of getting 110V /400watts in a widt range of frequency.

Yeah, just another tool to help us experiment with making HHO.

I will be posting the how to soon.

It is very simple, just need to change a resistor from 100K to 10K, and add a Potenciometer inline with the new 10k resistor.

for lower than 60hz will also need to replace a 0.1uf cap with a bigger one, maybe 1uf. will have to test this.

Ok, I was able to mod the husky inverter to output frequencies from 40Hz to 650Hz.

Using a transformer and a some caps we can also get a pretty good sine wave.

So what exactly can you do with this?

Well, just another tool, to experiment with.

so it converts DC to AC, and now you can vary the frequency, but you can't make gas with AC, so you'll rectify it, then you'll have pulsed DC with variable frequency, but it only goes up to 650 Hz, which doesn't give much room to find resonance.

I'm just trying to understand it, nothing against it, in fact because of this i finally understood how capacitors and resistors work in a circuit to control frequencies!

Well, I don't know if this will help, but BOB B. said several times that he used a modified inverter 400hz to 600hz to power his toroid cell...

So for those still trying to test BOB B. system, this should help.

If you rectify a 300 hz signal full wave that's 600 hz one of the Keely frequencies for splitting water.  Input that to the positive electrode and attenuate the negative electrode with 32,800 hz and there might be something to see.  Maybe not.

Good work jolt! That's a fairly clean sine wave coming out of the inverter. Did you modify anything to get the clean wave? What did the original sine wave looked like (before the mod)?

The output signal right out of the inverter is square before and after the mod, the mod only changed the freq. but when using a LC circuit on the ouput we can get a sine wave just like I did.

I used a series LC circuit. the LC combo was tuned for 650 Hz, and you can see that the wave is better at that frea, then when I run it at 420hz, the wave is distorted. I didn't have big enouph caps to tune it for the 420hz.

It worked

Very Nice work.  The main point here is you set out to do something and you were successful.  It may not have a large fequency range for tuning but what the heck I think its a way cool idea.  Nice work again!.

Please post the schematic for series LC circuit you used to clean up the sine wave.

Thanks in advance.
