摘要
介绍了一种新的控制策略,该策略可使普通的开关电源具有很宽输入电压范围,并以电流型控制芯片UC3845为例,论述了90 VAC^600 VAC输入范围的开关电源的设计方法。试验结果证实了该控制策略的可行性。
A design of switch mode adapter with large-scale operation voltage(90 VAC-600 VAC) is presented in this paper. This is done by changing its control mode and using typical current mode control IC UC3845 as an example. The experiments result shows the feasibility of this design.
