Ok Niofox thanks for the info. That coil that you did is pretty wide I did mine on a spool like bedini style.
Ok my setup is 1k 1/2watt resistor with a 0.47uf at 630v mylar capacitor and on the DMM 300v was giving at 0.8amps.
Ok thanks.

Groundloop's circuit is good but not efficient as bedini I can say. Today I tried the usual setup of bedini but with resisitors instead of rotor and again the coil was hissing. I cut some lenght from the base winding and an oscillation came. Yeeeees.
Ok I will try to amalgamate both circuits now. When I need a harsh pulse I put it to groundloops but when I need effiency turn to bedini.
Thanks

@crowclaw: tx for the circuit. Was wondering what other high side power switches one could use (perhaps an IRF device) - i am battling to find the infineon device you mention ie the BSP452?

Hi heathzap,

Sorry for delay in returning your question. Here is the link for the data sheet: http://www.datasheetcatalog.org/datasheet/infineon/1-Datasheet_BSP452.pdf

I have used this device for many other applications for supply switching etc. They are surface mount devices but can easily be adapted for conventional build projects. I'm not sure how easy they are to obtain as I have several of these to hand. I'm sure IRF devices are also readily available http://www.irf.com/product-info/ips/ for some reason I can't access this site it just hangs up so I can't check it out for you. If you have problems come back to me. Kind Regards

Hi Crowclaw, tx for the reply. I'm keen to try your circuit. As a newbie it's a variation of Daftmans circuit (on energetix) which I've been playing with. Do you have any pics of your working setup? My end goal is to help a poor rural community pulse charge their battery banks using lower power (therefore cost) PV panels. I will need to parallel up those high-side switches! Any advice would be appreciated. Tx for sharing your knowledge as you do!
