Abstract
- • Three phase dual-input split-source inverter (DSSI) is proposed for PV systems. • Compared to using one inverter for each PV source, DSSI provides reduced cost and size. • DSSI offers independent and efficient maximum power points tracking. • Experimental and simulation outcomes are presented. This paper presents a dual-input configuration for the three-phase split-source inverter (SSI) to be used with photovoltaic (PV) systems, it is denoted as DSSI. Compared to using one SSI for each PV input, the proposed configuration uses a lower number of semiconductors. Thus, lower cost along with higher power density can be acquired. The proposed DSSI inherits the brilliant features of the conventional SSI. This includes continuity of input current and high voltage boosting gain. The proposed DSSI offers independent control for the power extracted from each PV source. Thus, independent maximum power point (MPP) tracking is ensured. In addition, no circulating current between the input ports is generated. Simple modulation technique is developed for the proposed configuration. In addition, the control system design to ensure independent MPP tracking along with power quality requirements is illustrated. Comparative study with other dual-input topologies is presented. Simulation, experimental as well as real-time simulation results for DSSI are presented. The results show good performance under dual- and single-input scenarios. In addition, well dynamic performance is verified. Thus, performance at steady-state and dynamic conditions is validated for the proposed DSSI. An efficiency of 92.3 % is achieved by the experimental prototype. [ABSTRACT FROM AUTHOR]
