You are on the right track.A bridge driver will solve many problems. You can use all N-MOSFET and do not have to worry about both transistors conducting at the same time.This one is great driver:...

The main issue is the PV panel voltage drops the MPP voltage with solar power and on a 19.4Voc PV panel that Vmpp is now dropping from 14.5V@100%sun to 13.6V@50%sun to 10.9V@10%sun. So now you need a...

I guess the question is, is this a feasible design?The H-bridge buck-boost circuit is becoming quite common these days for your type of application so unless you have a particular reason to do all the...

There are several issues with your proposed schematic.You have your MOSFETs backwards. You want the drains connected to the coil, not the sources. Put the P-channel devices on top. The way you have it,...

Single inductor buck-boost idea for MPPT (maximum power point tracking)
Basically my inspiration is this guy's work. A buck converter that provides MPPT as long as the solar voltage is higher than the battery voltage. But I want to extract power to the battery even at low...
