Global MPPT for Interleaved Buck-Boost DC-DC Converter
This document describes a new technique of the Global Maximum Power Point Tracking (GMPPT) for DC-DC converter. The GMPPT time duration was cutting by fast setting out the Short-Circuit (SC) condition. The simple Proportional Integral (PI) regulator provides a stable control of the solar panels current. The simulation results confirm theoretical statements. The real Photovoltaic (PV) string was used for the experimental investigation. Shadowing conditions lead to the second local power maximum. Finally, the key points confirmed, benefits, drawbacks are covered.
