摘要

提出了一种利用输出电压反馈控制电流的电流型dc - dc变换器过载保护技术。这种方法被称为电压反馈限流(CLVF),它解决了下垂曲线的不随向性和短路电流失控两个严重的问题。采用状态空间平均法分析了CLVF的状态和动态特性。实验证实了这一分析

The overload-protection characteristics of the current-mode DC-to-DC converter: analysis and improvement
A technique for overload protection of current-mode DC-to-DC converters is proposed in which output voltage is fed back to control the current. The method, called current limiting by voltage feedback (CLVF), solves two serious problems: inarbitrarity of drooping curve and short-circuit-current runaway. The state and dynamic characteristics of CLVF are analyzed using the state-space-averaging method. The analysis is confirmed by experiments.<>
