Abstract
A maximum power point tracking charge controller for photovoltaic systems includes a buck converter for receiving the maximum power voltage from a PV array as input and for supplying voltage output to charge a battery bank while converting the voltage input to a voltage output that matches the voltage required by the battery bank for charging. The buck converter includes an inductor, a first switch, and a second switch comprised of a first MOSFET and a second MOSFET connected in series with a parallel diode, wherein the configuration of the second MOSFET is reversed from the configuration of the first MOSFET.
