Abstract :
A general method is presented for modeling multiport DC-DC converters. It copes with multiple inputs, multiple outputs and bidirectional ports, and is based on an averaging formulation. A matrix description is adopted, so the technique can be extended to converters with any number of ports. As an example, a three-port forward-flyback converter is analyzed using symbolic computation software (Maple V)
