Hi guys, I'm new to this forum, but if someone could help me out that would great!
I'm designing a solar charger for an iPhone for my circuits class, but my professor won't allow for the use of voltage regulators. This has made it a bit difficult to come up with a working solution.
My search so far includes shunt regulators, BJTs, MOSFETs, and relays.
The solar panel is 18V @ 12W, and I don't want to simply throw in a bunch of resistors to dissipate all that energy. The plan is to possibly connect a few USB ports.
