In this thesis, the brick DC/DC converter has the features of low output voltage, high output current, and high power density. A small-signal model of the resonant-reset dual-switch (RRDS) forward DC/DC converter will be developed. Simulations and experiments will be used to verify the presented model. The control-to-output transfer function of the RRDS forward converter is very different from the traditional forward converter. Thus, the design of feedback compensation could be achieved correctly by using it. Furthermore, the developed model for the RRDS forward converter can be applied to the resonant-reset single-switch forward converter (RRSS).
A small-signal model of paralleling the RRDS forward converters operating in the continuous conduction mode has been developed. A good dynamic performance of the current sharing circuit for the parallel application is very important since the microprocessors present highly dynamic loads to the converter. Based on the proposed model, the current-sharing network for the converter can be designed in terms of circuit parameters. The design methodology will be also given. Simulations and experiments will be used to verify the presented models.
