that method is simply to rectify the 122 vac from the TBC - then pass it through a PROPER voltage divider circuit to achieve a safe voltage level for the battery itself ( 14 vdc to 15 vdc - no more ) , then pass that through a DC smoothing capacitor and then straight to the battery circuit itself.
I said - why not? I already had available from prior art 4 each HUGE 4 amp
15KV power diodes. Vbid put me on to those years back.
so that is what I have been working towards and almost completed!
individual component photos attached!
I have already briefly used the assembled components and they work quite well.
I am now waiting for several more 10 Mohm resisters to drop the resultant DC voltage down a tad more. thought I needed only 8 of them but now I know it will take twelve of them to get the job done.
Should have thought about all this with years of past history in mind.!
It seems that any FWRB circuit for some reason RAISES the input voltage to a greater value like a Voltage Multiplier wouldIn this particular case the
122 vac is raised to 170 volts. yes, you read it right! that's why I'm waiting for a couple more resistors from Mouser.
as a side note, this FWBR setup I have now is the same type Marc B and turion (dave) should be using.
The part # is 2CLG15KV/4A . Both Amazon and E-bay have the available
at around 24.99 each. make sure it's the large screw connect on each end!
the resistors are Mouser # MOX92021000FVE 10 Mohm - about 14 plus change .
When finished and run I will give results as usual.
when I was briefly running this FWRB the total input was 120v @ .51 amp.
I said to myself , if that carries true all the way through into the battery circuit that will be amazing! that was driving the power supply , the ZVS
unit , the TPC , the TBC , the FWBR , the voltage divider , the smoothing capacitor --- awesome HUH1
Also note on the attached voltage divider circuit that the last resister seems unused ! however I believe it serves as a bleeder resister to keep discharging the smoothing capacitor, otherwise there would not be anything else to accomplish that? and also at the end of any run the capacitor would be left ready to kill you. notice the earth ground attached to the capacitor also!
Later BRO,
respects,
