초록
This paper presents a control method for grid-connected Active-NPC inverter systems. NPC (Neutral Point Clamped) is widely used in power conversion systems. NPC has a loss of switching elements and voltage imbalance. Active NPC has been proposed to overcome these drawbacks. ANPC changed the neutral diode to IGBT to reduce the switching loss. This paper modeled a grid-connected Acitve-NPC inverter systems and analyzed its performance. DSOGI PLL was used as a phase control method for precise control of grid link voltage. The proposed method is verified by PSIM simulation.
