Abstract
An efficient three-port interleaved boost LLC resonant converter is used as the basic converter unit of the modular DC grid-connected photovoltaic system in this paper. The bi-directional port of the converters is connected through a low voltage DC bus to solve the problem of unbalanced output power and voltage oscillation of each module in the system. The simulation platform of modular DC grid-connected photovoltaic system based on three-port interleaved boost LLC resonant converters is built. The operational principles and characteristics of interleaved boost LLC resonant converter are verified by simulation. The rationality and effectiveness of the modular DC grid-connected photovoltaic system and its voltage sharing control strategy are also demonstrated.
