Hi

I am trying to find a high voltage DC power supply. What I am trying to do is to pole some PVDF - first form it in the shape of a rod, then heat to 100c+stretch+apply DC bias across it so that it shifts to beta form for the piezoelectric effect.

I have been trying to find sources of high voltage DC for the same purpose. Unfortunately the poling requires pretty high voltage - 1million volts per meter. I can pole it in short segments but will still need around 6-10kv dc.

I have been looking around for the same and came up with the following options - flyback transformers, neon sign transformers and the rather promising items below.

I guess I don't need a lot of current and mostly need pretty high potential difference. I am leaning towards the bottom two since they seem to be battery powered and just feels less lethal :grin:

Also - please correct my calculation of power draw on neon sign transformers - if a 15000v and 30ma neon sign transformer is connected to mains, won't it draw (15000*30)/1000=600A !

Any suggestions for such a power source will be greatly appreciated.
Thanks
 

Hi,

(15000*30)/1000=600A !
There are two mistakes.
1) Voltage x current never gives current again.
2) Your mathematics is wrong

Of course. Doh! That is so obvious now that you mentioned it ..

Thanks
