| Abstract: | The small signal mathematical model of push pull DC/DC converter is constructed by applying the state space method,and the closed loop system block diagram and transfer function are proposed.Then a system is designed and corrected with automatic control theory. The effect of PI correction on the system property is discussed, and PI correction is compared with other correction methods.The simulation results indicate that the small signal model is correct and feasible. |
