Abstract :
In this paper, the authors present a dynamic modeling technique for a parallel connected DC-to-DC power converter unit (DDCU) using the improved Weinberg topology. The state-space averaging approach, used previously for the single stage converter, is used here for the modeling of two parallel connected Weinberg converters. The closed-loop controller design is based on the average current sharing method used in distributed power systems. This model can be used to obtain the closed-loop frequency response and transient responses for load currents and output voltage. Based on a specific design example, a PSPICE simulation for a two-parallel Weinberg converters is presented
