Hey guys.
I am in need of a regulated 1000 volt power supply, that can be easily controlled with an op-amp. I intend to build the op-amp booster circuit listed in Figure 10, pages 7-8 of this document from National Semiconductor:
Its listed as the "son of godzilla booster" or "1000V 300mA Booster"
This is a 1000v, 300mA output, op-amp booster circuit, which uses regulated +15 and -15 volt sources, and using a controller IC and some power PNP transistors, it drives a step-up transformer at 20kHz, to step up the 30 volts to 1000Vdc after its sent to the full wave rectifier. The only problem is that this ty-85 power toriod made my Triad Magnetics, isnt made anymore, so I need to make my own 20kHz 300 watt transformer.
I found this EFD30 transformer core, which was rated for 297 watts on the datasheet, and I was wondering if this would be a good core to make my transformer on.
What want to know, is what impedance's should i be looking at for my primary and secondary windings, and how close to core saturation should I be? And whatever else essentially so I need to know about transformers, as this will be my first time winding one.
in case anyone was interested, here is the information on the ty85 transformer that the circuit calls for: (its kinda hard to find, you have to scroll down and by trial and error find page 22, which has the ty-85 transformer listed)
any help will be greatly appreciated.
thanks,
Robby
