Abstract

The new step-up capacitor grid is connected to the solar photovoltaic (PV) having a voltage balancing converters. It’s suitable for Neutral-Point-clamped (NPC) Multilevel Inverter (MI). To balance the capacitor DC link voltage effectively we've got to use switched capacitors. By using balancing converter, we will enlarge the higher levels and also by boosting input voltage we are able to see the upper levels of voltage without using magnetic components. This attribute allows operating the input and output voltage by self-balancing. The balancing converter for NPC multilevel inverter-based solar PV system is operated by using vector scheme control. PV system incorporates a Maximum power point Tracking (MPPT) and it's executed in Matlab power system. The output of the simulation result topology can successfully balance the DC voltage and excess power from grid. The injected power within the grid can vary the solar light with active performances.

Keywords
