Bedini pulse charger buster

[mscoffman]

The 2n2222 transistor is a low power transistor. Lets
esimate approximately 1 watt internal dissipation.

The 2n3904 - 2n3906 are medium power transistors that are
pnp/npn pairs with similar specs. Lets estimate 6Watts maximum
internal dissipation.

The 2n3055 is a general purpose audio frequency power
transistor Lets estimate 10 to 20 watts internal power
dissipation.

If you think you are going to be dealing with HV pulses
you may want to consider using a power (metal case)
transistor built for Horizontal Deflection Final Output (CRT)
Service. These should be more robust in the face of high
voltage pulses and be more consistent behavior one-transistor
to-the-next than the 2n3055's.

You will need a power transistor (metal case) transistor
for running at 12 volts and above if you want to use a low
resistance coil of less than 50 Ohms dc internal impedance
or so.

All of the above numbers are estimates, your milage may vary.

this CRT transistors you are mentioning... do you have any part number in mind?

thnx

Usually with the 2n3055 a neon bulb is connected across it for HV  pulses  so that transistor is not burned off in Bedini motor.
Thanks

unfortunately my job prevents me to give more time into this and probably for next two weeks no progress will be made with my setup...

later..

hi all,

I just wanted to say that for me, work on this Bedini buster project is finished.
I am now giving my attention to Orbo..

my rotor setup for this "buster"

http://www.overunity.com/index.php?action=dlattach;topic=8017.0;attach=37842;image
looks usable for Orbo replication and my "buster schematic2"
http://www.overunity.com/index.php?action=dlattach;topic=8017.0;attach=37626;image
looks fairly similar to http://www.overunity.com/index.php?action=dlattach;topic=8411.0;attach=40523;image which is used now by one user in Orbo replication...

and my goal was to recover back EMF back to battery with this schematic and not to chase some non existent effect...

this mentioned Orbo circuit recovers back EMF in toroid trigger circuit of Orbo to minimise input power or to enhance eficiency... which is nice

bye
