|
摘要
为了解决常用开关电源输出纹波较大的问题,尤其是因整流而产生的二倍工频纹波所带来的影响,提出了带平均电流内环和电压外环的零纹波Cuk变换器的双环控制系统设计.首先按照Cuk升压变换器主电路基本工作参数,设计并选取了相应的主电路元件参数;然后根据带耦合电感的零纹波Cuk变换器的小信号模型,对该变换器的控制系统进行了具体设计;最后在Matlab/Simulink环境下搭建了仿真实验平台.仿真结果表明该控制系统可实现输出电流低纹波,从而验证了该控制系统设计的合理性.
In order to solve the problem of common switching power supply output ripple, especially the influence of duplex frequency ripple caused by rectification, this paper proposes a double-loop control system design of zero ripple Cuk converter with average current inner loop and voltage outer loop. Firstly, according to the basic work of the main circuit of Cuk converter parameters, the paper designs and selects the corresponding parameters of the main circuit components; and then according to the small signal model of zero ripple Cuk converter with coupled inductor, designs the control system of the converter. Finally, the paper builds the simulation platform in Matlab/Simulink environment. The simulation results show that the proposed control system can achieve the output current with low ripple, thus verifying the rationality of the system design.
