| Abstract: | In order to improve the current stability and reliability of the push-pull converter,this paper analyzed the push-pull DC/DC converter operational principle,and on this basis,built its small signal mathematical model.With imposing the current-mode dual-loop control strategy into its control system,improved the system dynamic response and protection ability.It has given the design process of the control system of push-pull converter,simulation and experimental research also has been done in the paper.The simulation and experimental results showed that,in view of the push-pull converter,the dual-loop control strategy has got a good dynamic and static control performance. |
