Current-mode control for load sharing converter systems with dynamic current distribution

A current-mode control scheme for load sharing converter systems with dynamic current distribution is introduced. These converters may be driven by different sources with various minimum available power levels. With this control feature, the system is able to dynamically distribute the total output current among the converters according to these levels. A converter with a higher power level will deliver a larger portion of the total output current. The current distribution control algorithm and the system stability are described and analyzed in detail. These analyses and descriptions are confirmed with computer simulation results
