A forward converter topology with independently and precisely regulated multiple outputs

A forward converter topology with independently and precisely regulated multiple outputs is presented in this paper. In this topology, each regulated output has its own feedback control circuit that controls the appropriate synchronous rectifiers in the pertinent output stage. All output circuits are voltage-decoupled from each other, and the cross-regulation between the outputs is eliminated. Steady state analysis as well as small signal modeling is performed to understand the topology and to provide design guidance. A prototype circuit with two outputs is built, and experimental results are presented for proof-of-concept.
