Abstract

This paper presents a Model Predictive Current Control (MPCC) technique for 1-phase 4-level Grid Connected Asghar Inverter (GC-AI) and basically it consists of four unidirectional switches, two discrete diodes, four capacitors, and one dc source. It offers self-balancing of capacitors, boosting ability, and well suitable for photovoltaic applications. In grid connected operation, to inject the grid current conventional dq-frame current control technique requires more number of transformation blocks, complicated tuning proportional-integral parameters, modulation stage and finally it produces sluggish transient response. To curtail the complexity of control, a simple MPCC technique with needless modulator stage has been implemented without consideration of weighting factors, and it also provides an excellent dynamic performance. The objective of tracking reference current along with balancing of capacitor voltages have been explained vividly using predictive algorithm in both RL-load and grid-connected cases through PLECS platform.
