John Bedini Solid State Charger, built according to schematic from FEG book. After some adjustments with duty cycle and capacitor pulser finally running as designed. Quite powerful "little beast" :)
Circuit running of 12VDC can charge few smaller or couple bigger batteries. Connecting additional charging batteries doesn't increase input, which stays between 0.1 - 0.15A, depending on battery condition (sulfation). Oscillating part runs on TIP41(about 2.5kHz), 555 is separated from power switch by optocoupler. This setup has inverted SCR pulser, which means that positive from bridge rectifier sits on battery terminal and negative is pulsed over battery terminal by SCR. I have this running continuously for the past 2 months (with some adjustments done). I can feel pulses while holding one disconnected clamp - video may not do the justice but the spark is big and loud.

Big Thanks to John Bedini for sharing.

Thanks for watching.

  • Is that the charger on page 46? nice work!, I was going to have a go at one my self, now i have to thanks.

  • @GeorgeyNico  Yes,

    Thanks

  • Thank you for your kind comment Tony. This was one of early prototypes. I obtained better results with heavier wire (#18) trifilar and multifilar solid state. I charge off the bridge, without cap pulser and they work well with large batt's. I was forced to list other trifilar on eBay since I can't finance any other work. Meet me at Energetic Forum or PM. I'll help you while I still can.

  • help me out please i have six 2v 270ah battery do i need bigger gauge coil?

  • @MrPounal007 Are you connecting them in series to get 12V bank? I still have trifilar made with AWG 18 and aircore (no iron) and it works fine with car batteries but for bigger Ah I use six filar solid state with same wire. It takes less time to get the job done. I have only 100 feet of each strand of wire on both systems. When I increase an input to >20V the charging is impressive but trigger resistance has to be adjusted accordingly. The wave form is important.

  • i have one of the book but it dont tell me  what voltage cap

  • @MrPounal007 For solid state use small 1 - 6uF. You'll need to adjust pulse timing and cap size to get 1 - 2 discharges per sec. while keeping voltage between 15 -22V max. Hitting battery with higher voltage doesn't mean better charging. Sometimes even 2.5V over the battery V will be enough. I was getting good charging with 22V pulses, 2 per second.

  • I think you are getting good results with your charging systems. Your work looks very organized and neat! Would this solid state design work well for charging heavy 12V batteries used in trucks and/or heavy deep cycle batteries?

    Can you please post a schematic for this design or give us a link to it?

    Thanks and have a great day!

    Tony

  • @petrovski1948, I don't have this prototype anymore but spool was about 3"x3" with 5/8" core (welding rods). I used AWG#24 wire, about 150' each strand, all three twisted together. And yes to your second question.

    Thanks

  • Excellent work. What are the physical coil former details please such as diameter and length of coil former.. Number of turns and gauge of wire. Also, are you using variable controls to adjust 555 timer pulse? Thanks
