摘要：
This paper presents a single-phase single-stage inverter for PV application. FIR (Finite Impulse Response) digital filter is used to replace the conventional combination compensator as repetitive controller. Combined with traditional proportional-integral (PI) control technology, compound current control improves its dynamic performance. A 3kW inverter is designed by using the compound current control, Simulation and experimental results indicate that the THD of the inverter is much little. Furthermore, both the grid voltage and the grid current are in phase at near-unity power factor.
