A novel single-phase interleaved Bi-directional inverter for grid-connection control

This paper propose a novel single-phase interleaved bi-directional inverter topology. The bi-directional inverter can operate in the grid connection mode (GC) or the power factor correction mode (PFC). The Interleaved Inverter have several advantages such as the increase of the power capacity, the reduction of the current ripple, the decentralized power switching component losses and heat dissipation. In this new topology, we can choose the lower current stress for power switch component and increase the switching frequency and system bandwidth for the reduction of the output filter size and cost. The predictive current control strategy improves the total current harmonic distortion on the grid side. Finally, The topology and current control strategy is verified by using the simulation program.
