| Abstract: | The work characteristics of forward converters are described.Via the a verage-state-space method,the small-signal model of forward converters is const ructed.The design of the controller is given to be used in this converter with the maximum control bandwidth of 10 kHz as well as an adequate phase margin.A c losed-loop simulink model for the converter is constructed and the dynamical per formance demonstrated.Simulation results show the feasibility of the design. |
