| 摘 要： | 介绍了一种全桥移相式开关电源补偿网络的最优设计方法。在Buck型PWM变换器小信号等效电路模型的基础上得到全桥移相式ZVS-PWM变换器小信号等效电路模型,进而导出其主电路的传函模型。以阶跃扰动下电压误差加权平方积分为目标函数,采用连续优化算法ALAPT和离散优化算法MDOD相结合的技术为补偿网络参数寻优。仿真结果验证了该方法的正确性和有效性。

| Abstract: | This paper introduces an optimization design method for the compensation network of phase-shift full-bridge switching power supply.Based on the small-signal equivalent circuit model for the Buck PWM converter,a smallsignal equivalent circuit model of the phase-shift full-bridge ZVS-PWM converter is obtained,thus bringing about a main circuit's transfer-function model.Taking ISE index as the objective function,optimal parameters of the compensation network are obtained by way of ALAPT and MDOD.The simulation results prove the correctness and effectiveness of the given method. |
