Use for the Tesla Switch

[sujan_ms]

That is correct.

Thanks.

what value should i set the R9 i.e 10K pot so that i get accurate pulses....??

hey jeff thanks on the specs....

but in india we use 220v ac so according to you in the circuit diagram on the left side of the transformer i.e CT SIDE transformer should be 12/6 volt CT and on the other side it should be 120V AC ryt??? pls let me know...sorry im lil slow in understanding.....

That is correct.

Thanks.

Hey thanks for answering my questions . So what kinda transformer should I use can u tell the specs if the transformer coz here in india we won't get it readily so I need to get it done .I need the current rating and type of the transformer.I.e is it AC TO DC OR DC TO AC

Hey thanks for the circuit, but can I use this for my application, as I mentioned it's for charging a battery of 12v just like that of a car battery. And in my project I'm using only one battery and no swapper so just confirm on this to me so that I can proceed.

One more thing I wanted to ask you is why have you eliminated one of the switching circuit and I also didn't understand the logic in using diodes D5, D1 and D2 what is the purpose of centre tap transformer and does the
transformer convert from DC TO AC or VICE-VERSA
can you please explain the logic. In the BOM sheet the values of the components and program still remain the same for this circuit also right???

Ok, I'll try and answer your questions. Yes this is a 12V charger for the lead acid batterys. Eliminating the high side switching reduced cost and gained performance. D5 and D2 prevent reverse polairity. D1 steers positive and negetive pulses from the transformer. DC is feed into the transformer but is oscillated in postive and negative pulses, imulating AC. You'll note the transformer is turned around thus becoming a step up transformer. Yes the component values should be the same.

Thanks.

Hi Bits, amazing work as always

Great idea with the next gen tesla switch

Now, tell me if I understood correctly: On the original tesla switch, the big difficulty was in matching the load to the charge rate. If these were not perfectly matched, you would either discharge the batteries or overcharge them. Correct?

With your next gen you have separate modes of operation: charge / power load. Very nice.

Question: When powering the load, is there still pulsing going on? To try to keep the batteries charged even while loaded?

Best,
Alex

Thanks Alex, yes in the original TS matching the load was critical but at the end of the day, that batts didn't gain. In the New TS, the load and charging are seperated.

Hope this helps

jus have a look at the circuit

Here is the most recent rev. You can power this for testing purposes off of J3. This device will also run when a source of 12V - 15V is applied at J2. R9 is part of the sensing circuit install on this rev. Also note other changes.

Thanks.

[sujan_ms]

Which version are you looking at? At the moment, I do not have access to my drawings. If you can repost my drawing I'll be able to discuss.

Thanks.

Hey thanx for replying jeff , in the BOM sheet you have given R9 as a 10k pot but i coudnt identify this in the "inverter voltaic amp" circuit , and can i know what J2 is used for , and i see that the power supply J3 is directly going to diodes D2 & D5, is it only for testing purpose, and will the adapter O/P be in DC or AC i.e output from the wall adapter.

What i understood is that along with the wall adapter we also use the J2 for any range of input from 12-33v , here im thinking of using a SMPS to depict the solar panel act. since soar panels cost more here in india.
any other alternatives pls suggest.

J3 is for a wall adapter supply to power the board for testing. I think your question for the device in the lower most left hand corner is DB9. This is the programming port for the chip.

Hope this helps,

Thanks.
