After some study with simulations, I've been trying to find a way to increase transformer current by increasing the operating frequency and decreasing it's size, mass, cost, and turns. It seems to make sense that I can make a much cheaper and higher current transformer by doing the following, and I would like some guidance to see if I'm on the right track:
My goal is to:
It seems to me that if this was practical and cost effective, it would already have been done, but it's worth a try. My draft schematic is attached.
- Use a higher operating frequency- 50-100kHz or so?
- Use a higher frequency core type- ferrite or powdered iron?
- Use relatively fewer turns of low gauge wire to support higher current, and thus lower inductance so it's able to operate a high frequencies.
- Use a simple transistor with an oscillator to switch the primary on and off
- Possibly be able to modulate the oscillator depending on the load of the secondary, perhaps to the point of shutting off it there is no demand.
My goal is to:
- Reduce weight, volume, cost, etc.,
- provide much higher current in a smaller package, and
- be able to select a precise voltage by winding it myself.
