I am trying to design a buck converter for a PV panel. I know that I can purchase a commercial MPPT or even find a chip that offers MPPT. I am planning to build one using a microcontroller, temperature sensors, etc. for a project. I would like to simulate a basic boost converter with the model I have for my PV panel in LTspice. Are there any clever ways to implement MPPT in LTspice on a simple buck converter? Attached is an image of my schematic.
Also, I cannot get my high side switch to fully turn on. I'm using a PMOS for the high side switch because the full implementation will be high voltage. I'm using an NMOS to pull down the gate voltage so the NMOS is actually the one being controlled and I can do it with a small driver.
