Abstract
High integration, high power density has become the development trend of power supply. Computer, automobile and aviation often require multiple output power, in order to meet all kinds of load, and the filter of current type output for the power supply should be a larger challenge. The input voltage becomes wide and high, and each output is low voltage with large current. Compared to the non-isolation topologies, isolation topologies have better ability of step-up/down. In this paper, the two-stage converter structure is used, in which the forward stage is used to step down the amplitude of the input voltage, and the backward stage achieved precisely multiple current output with independent control. Also optimization and design of the transformer and output filters have been made clearly, to solve the problems of cross regulation, stability, and dynamic response in traditional structure. Finally, four-current-output prototype with 80-100V input, 8A/10V, 8A/10V, 6A/20V, and 6A/20V outputs is built, and the analysis is verified by the experimental results.
