I am completely new to this stuff. Have general circuits completed, am at an internship designing a switching power supply (specs below) to control a 24VDC coil activated relay with a 30Amp relay. I want to use a buck/boost converter to do the trick. I am unsure about how to pick which size fixed cap to use in the converters??? Or any cap sizes for anything. See the tag for schematic, note the SW1 OFF schematic. I figure after asking a few times I will start getting a feel for what might work and what probably won't. If you learned a different way, please let me know where I can look for resources. Searching online I don't find concrete answers, I find intuition based answers.
Also note that my goal is simply to smooth out the switching frequency to deliver a constant voltage to the load, not actually add power. I may need to do that for the buck booster, but as seen by the schematic, I am working on the buck converter now.
Thanks for helping the newbs.
