Control method for reduction circulating current in parallel operation of DC distribution system for building applications
In the large system such DC distribution for building, the method that a number of modules converters operation in parallel is commonly used. When parallel operation, circulating current is directly related to the loss of the entire system. Accordingly, each module to share the same current is the most important for the safety of the power system. In this paper, control method for reduction circulating current in parallel operation is proposed. Thus, Response and operation of steady-state with parallel system was verified by simulation and experiment.
