Greg. What

I did not analyse the complete circuit but if the battery is 12V then the LM7812 will not work here.

I don

Yes, I figured that was the case after I looked around in the Blanchard place. You just rest for a few days and it will pass. Pour some good stuff in your tea or coffee and you will feel much better shortly. It

Is the residual voltage a problem; is the production of hydrogen greater than the idle consumption? So, the P-channel is hard to get at your location. The Blanchard site H-bridge has P-channel AND N-channel MOSFETs. I agree this gets a bit complicated compared to an ordinary bridge. Maybe someone else reading this have a suggestion. You can use a 555 instead of the ICL7660 to create a low current negative supply if you need one. How frequent must the electrodes change polarity to keep nice and clean? I know this is answering questions with questions but I like to know as much as possible to give you the best answers I can come up with.

Rhonn, Here are some clues: http://members.misty.com/don/f-dim.html

Hi Rhonn, How much power do you need (W) ?

Kevin, No not PWM, but phase control. If you have Power Point installed in your computer, here it is: http://www.eas.asu.edu/~karady/360_stuff/Lectures/360_Topic_7_Power_Electronics.ppt If not check the PDF, sorry that the pages are sideways. SCR_phase_cont..pdf

Kevin, That

Audioguru, Oh, I forgot to mention I have a ton of RFG50N05 so it would be nice if they were usable . Its not a must I can get some new if required.

Audioguru, Sounds good, I am looking forward for a schematic to be posted sometime in the near future.

Sasikumar, If you post the circuit you

I

Audioguru, I like an inverter for car use and I need it to be sine wave output 230-240VAC 50Hz @ 300W. It would be very nice if it where variable 0

Amen!

Audioguru, Only to cool guys! 8) Ante ::)

Thanks Audioguru, I better look elsewhere for a transmitter circuit, I couldn

Why is this transmitter called 4W it can

Audioguru, What

Audioguru, The man says

Sasi, Look good, a few points: Why not use a 230VAC changeover relay, this will lower the cost and component count (one transformer, one rectifier, and one cap). At least remove the capacitor to get a quicker changeover? But don

Rhonn, Yes 100VA is almost 100W but you can

Quantum, I found a site for you with nice experiments; there is a small problem though. Or maybe not, can you read German: http://www.hcrs.at//MIKRO.HTM Ante ::)

Hi Rhonn, 100

The PWM circuits can be
