Abstract :
Various dual-converter configurations operating in the circulating current mode are compared for use in constant-voltage DC regenerative power-supply applications. Three types of dual-converter configurations are discussed. The design of these systems, including the circulating current limiting inductors, is provided. System components were designed using the three dual-converter configurations with the following specifications: (1) AC supply, three-phase, 115 V, 60 Hz; (2) DC output voltage 135 V; (3) maximum DC load current, 100 A; and (4) ratio of the allowable average circulating current to the maximum DC load current=0.2. The results are experimentally verified
