| 摘 要： | 根据双管正激DC-DC开关变换器的基本原理,在低频、小信号、小纹波三个假设条件下,利用状态空间平均法以及欧拉公式建立了双管正激开关变换器的动态数学模型,根据建立的数学模型设计了补偿校正网络。在此基础上组建了电压型闭环自动控制系统,仿真和实验结果表明系统具有良好的动静态性能,验证了该数学模型的正确性以及控制策略的合理性。

| Abstract: | According to the basic principles of two-transistor forward DC-DC switching converters,under the hypothesis of low-frequency,small-signal,small ripple,the state-space averaging method and the Euler formula were used to establish a dynamic mathematical model of two-transistor forward converter switching.Based on the mathematical model,the compensation and calibration network was designed.On the above basis,a voltage closed-loop automatic control system was built.The simulation and experimental results show that the system has good static and dynamic performance,verify the correctness of the mathematical model and the control strategy is reasonable. |
