Abstract :
This paper presents an approach to parallel operation of voltage source inverters. Different to traditional strategies, this method employs no interconnection between inverters except the output part. Taking advantage of this technique, every inverter in the parallel system shares load appropriately as well as operates independently. Furthermore, parameter difference among inverters can be compensated automatically to guarantee precise load sharing. Principle of this control scheme is discussed on aspects of frequency, phase and voltage regulation. Simulations and Experimental results are in accordance with analysis.
