A peak-buck peak-boost current mode control structure and scheme for a synchronous four-switch and non-synchronous two-switch buck-boost regulators sense input and output voltages to smoothly transition between buck mode, buck-boost mode, and boost mode for high power efficiency and low output ...
Voltage Mode就是三角波幅度倒数, Current Mode是电压和电流的综合),Kf和Kr是考虑了Vg和Vo的扰动影响, 其值很小, 一般忽略没有大的影响. Hv是电压反馈环, Hi是电流采样系数, 负号表示负反馈. 如果是采样电阻的CIC(Current Injection Control)法, Hi就是采样电阻,如果是电感电压的SCM(Standard Current Mode)法...
电源反馈设计速成篇Z八:建模篇Peak Cunein Mode图1为Peak Cuirent Mode等效小信号模型.Vg为输入电压,Vo为输出电压,io 为输出电流,1L为电感电流,d为占空比,Vc为反馈控制电压.Gvg为Vg到Vo的传
The boost type dc-dc converter is used for compensation of dc bus voltage in the dc power feeding system such as the renewable energy system. It should be operated stably to improve reliability of the system. The peak current mode control is applied to operate stably because the boost type ...

The discrete iterative map models of peak current-mode (PCM) and valley current-mode (VCM) controlled buck converters,boost converters,and buck-boost converters with ramp compensation are established and their dynamical behaviours are investigated by using the operation region,parameter space map,bifurca...
In this paper, the boost-flyback power converter is controlled by peak-current mode with compensation ramp. The closed-loop analysis is performed to guarantee operation conditions such that a period-1 orbit is attained. The converter is considered as a piecewise linear system, and the closed-...
Buck current loop 15 Boost Regulator Example For the peak current-mode boost example, comparisons of results from the switching circuit of Figure 14 were made to the linear model of Figure 23 using the sampling-gain term...
