A robust model-following regulator for boost dc-dc converters with average current mode control is proposed in this paper. The aim of the proposed circuit is to reduce the closed loop output impedance and audiosusceptibility of the converter without the need of a high bandwidth in any of the ...
In this paper, Inductor Average Current Mode Control (IACMC) is proposed to regulate single phase Power Factor Correction (PFC) Buck-Boost Converter (BBC) operated in Continuous Conduction Mode (CCM). The Proportional-Integral (PI) controller is acts as an outer voltage loop and the IACMC is...
This is an ac-dc boost converter stage, which converts the ac input voltage to a high voltage dc bus and maintains sinusoidal input current at high input power factor. As indicated in Figure 1, three signals are required to implement the control algorithm. These are, the rectified input ...
Conventional peak current mode control actually controls inductor current. As normally used for output current control, it is most effective when applied to a buck regulator where the inductor is in the output. But for flyback or boost topologies the inductor is not in the output, the wrong ...

A controller design methodology for an n-stage cascade boost converter is given using average current-mode control. This class of converters has n-LC filters; thus, it will exhibit 2n-order characteristic dynamics. The proposed scheme employs the inductor current of the input stage and the capaci...
