Next time I make another I’ll add volt and zcr gauges. Unfortunately, due to the circuit having no smoothing whatsoever, any battery would be subject to so much ‘ripple’ current that it would be destroyed in a short space of time! I am trying to make a charger for my robot which has 4 6V SLA batteries 2 in series and then in parallel for 12V.

Hi, can the circuit be run from a 12V dc source or does it have to be AC? How can I use a 12vdc input to charge a 12vdc battery? How to get the instrument calibrated? An error occurred, your message could not be sent. I built this circuit more than 20 years ago and I used two SCR and a bridge graetz. wcr


Posted February 12 edited. In this circuit you suggested sc ac Transformer, not to mention that the diodes will lower the output voltage also lead acid battery isn’t at 12V even when discharged, its around somewhat Can I use mA transformer? Hi, can you use a higher amp transformer for say a 12AH battery without changing other components? I say a BIG weldone to the site management.

Gate Trigger Current Igt. Ps you are doing a great job. By the way the circuit does not work with Full-wave rectification right? Time to charge is not an issue at all.

If this can do it, what needs to be change? Hi, Thank you for sharing this knowledge.

Do you have any suggestions for more common components that will work as replacements for both? Thyristor TO V 0. An LED indicates when the battery is fully charged.

Please I will be glad if my question is answer as soon as possible.

What about replacing D1 by a rectifier and Q1 by a thyristor? This is great but for 12v Ah battery it does not work? Please tell me if this charger can be left to charge a battery for indefinined time,or it need other circuits? How do i modify this circuit. Also the price of this kit.

Edited February 14 by marcelv. Thanks for the information. Thank you for the great Circuit. I need your advise sir, and reply me, Thank you. In collaboration with Intertek, Distrelec is offering a calibration service bdx49 new electronic test and measurement instruments. On Q1 pin 1, 8.

Can I use circuit for three phase delta connections: Why is this question coming up again? We also connected 12v chargable battery at output but we are not getting 12v at the output. We are connected 3v red LED. Does the current self limit in case the battery bxr49 flat?
