Well I thought I would do a few more experiments with switch-mode power supply type circuits. This time I thought I would try to design and make a buck boost converter using a TL494 IC and a few other parts. I can't take full credit for the circuit though, as it was inspired by a circuit I saw in another YouTuber's video. It didn't go exactly according to plan, the "buck-boost" part works a treat but as for trying to get regulated output via feedback to the PWM, well that didn't work all that well but I still got a few somewhat interesting results. SCHEMATICS ARE IN THE VIDEO, so please dont ask for them, just take a screen-cap of the video if you want them. I'm not done with trying to make this work properly, I still have some ideas to try out, so if I get it to work there will be a follow up video some time in the near future.
