MODIFIED PERTURN AND OBSERVE OF TRANSCONDUCTANCE TRANSFER FOR MAXIMUM POWER POINT TRACKING IN PHOTOVOLTAIC SYSTEMS

摘要

In one example, a method of operating a photovoltaic (PV) system substantially at a maximum power point is described. The PV system includes a PV module and an inverter coupled to the PV module. The method includes controlling an output of the inverter as a function of a trans-conductance of the PV module over time.
