摘要
针对升压型全桥移相零电压开关PWM变换器,提出了一种基于电压模式控制的控制器的设计方法。利用PS-PWM变换器的开环小信号模型,综合考虑了输入电压和负载电流的扰动,得出系统的电压模式控制框图,并根据其原理推导出系统的闭环传递函数,分析得出控制机理和控制器的设计方法。经Matlab仿真分析和实验验证,该方法设计的控制器具有良好的控制效果和鲁棒性能。
In this paper,a voltage mode controller for Boost type Full-bridge Phase-shift Zero-voltage-switch PWM Converter is analyzed and designed.The voltage mode control block diagram is abstracted from the open loop small-signal model of the converter, considering input voltage and load current disturbances.Then the close loop transfer function is derived and the control mechanism is got based on the principle of mentioned method.Clarified by Matlab simulation and experiment,the design method for PS-PWM converter obtains good robust control performance.
