Abstract :
Recently, there has been increasing interest in the parallel operation of DC-DC converters for reasons of increasing system reliability, facilitating system maintenance, allowing for future expansion, and reducing system design cost. In order to achieve desirable characteristics when operating converter modules in parallel, this paper proposes a unified systematic approach for modeling of parallel DC-DC converters with current-sharing control. The derived analytical results are verified by simulations of a peak current-mode (PCM) controlled buck converter.
