Rezumat

This paper presents brief overview of the use of modulated neutral-point-clamped (NPC) inverters (NPCINs) with specific control and modulation schemes and techniques as basic workhorses of transformer-based grid-connected photovoltaic (PV) stations. Therefore, the using of NPCINs with modified schemes and algorithms of synchronous PWM insures providing in PV installations both synchronization and symmetry of the winding voltage of power transformer, and minimization of common mode voltage in these renewable energy systems. Examples of the use of modulated NPCINs to adjust several topologies of NPCIN-based PV stations with multi-winding power transformer are presented.
