A precisely regulated multiple output forward converter topology is presented in this paper. In this topology, each output voltage is directly and independently regulated by its own feedback control circuit that controls the appropriate synchronous rectifiers in the pertinent output stage, while the main switch is feedforward controlled. Thus, there is no cross regulation between the outputs, and design of each output becomes straightforward. Steady state analysis is performed to understand the topology and to provide design guidance. A prototype circuit with two outputs is built, and experiment are carried out on this prototype and the results verify the concepts and design
