I have finished the construction of an HV supply (that was in part the subject of another thread) and it is producing hefty sparks (and where a short video of it working can be seen at: https://www.dropbox.com/s/n2z0de5k1pu6fk4/Coil HV.MOV?dl=0 )
My query is regarding the resulting voltages that I measure with a 1000:1 voltage divider probe (see pics). By adjusting the primary voltage (with the MJE3055) I get a range of secondary voltages from +3.8kV to +6kV and -16.4kV to -33.2kV as shown in the images. This negative voltage, with its shorter duration, I presume is some form of BackEMF that I would like to remove from the supply to the plates of my HV plasmolysis cell so there is only one polarity hitting the plates.
Is there an easy way to block these? I imagine most diodes won't take the hit but there might be another way. Alternatively, at some stage, I might need to remove the positive peaks and just keep the higher value negative ones.
Thanks
