I want to make a boost converter which uses the least ammount of parts possible, and triggers itself.
The idea is to have a "sense" or "trigger" coil within the main inductor, that way when it reaches saturation Faraday's law dictates that the voltage falls to zero on the sense coil. I would like this to trigger the switch to open causing the magnetic field in the main inductor to collapse.
Im good with physics, but have not delved too far into the world of electronics. I can use a freq gen, or 555 or any pwm chip to manually set the frequency, but I would really like to simply use a transistor or mosfet.
Does anybody have any ideas on how to get the sense coil to trigger the opening of the switch? what type of switch do you recomend?
Sorry for not giving more specifics, however I would appreciate awnsers whose concepts are applicable to other projects as well. Im sure there must be some Tesla coilers out there with similar designs,
Thanks in advance!
