TLDR
In this paper, the authors developed a new control technique which allows paralleled inverters to share linear or nonlinear load in a distributed AC power supply system, which automatically compensates for inverter parameter variations and line impedance imbalances.Abstract:
The authors have developed a new control technique which allows paralleled inverters to share linear or nonlinear load in a distributed AC power supply system. This technique does not require control interconnections and automatically compensates for inverter parameter variations and line impedance imbalances. Experimental results are provided in the paper to prove the concept.read more
