Abstract :
Electric power conversion systems composed of several parallel-connected converters have advantages for designing high power conversion systems and standardizing systems. In this paper two converters providing different currents are connected in parallel. Suppression of the cross current which circulates between the two converters is examined. A method for designing multi-converter system is proposed. A strategy to decide a current allotment ratio is included.
