Abstract

This paper presents a simulation test for an LLC resonant inverter used in partial shading conditions in differential power processing (DPP) structure. The proposed inverter is designed as a voltage equalizer and voltage multiplier with two switches. The purposes of the proposed inverter are to find the global maximum power point (GMPP) and to improve the overall efficiency of the photovoltaic (PV) system with two high-switching-frequency switches. The simulation results in PSIM illustrate the improvements of the proposed inverter based on the differential power processing (DPP) system. The local maximum power point (LMPP) disappeared and the efficiency of the whole PV system has improved.
