The present invention relates to an average current controller, an average current control method, and a buck converter using the average current controller. The average current control method comprises a step for determining whether or not a current level of a main switch reaches an average ...
Dynamics and stability of average current-mode control of buck converters areanalyzed by sampled-data and harmonic balance analyses. An exact sampled-datamodel is derived. A new continuous-time model "lifted" from the sampled-datamodel is also derived, and has frequency response matched with ...
An example buck converter in continuous-conduction mode is considered. A comprehensive characterization is presented for the proposed scheme. An overall dc and small-signal analysis of the inner current loop is performed. The current average current-mode control methods suffer from switching instability...
Average-input current-mode control (AICMC) is a new control scheme for shaping the input current of a buck converter in a high-power-factor rectifier. AICMC is presented along with a continuous-time model that includes sampled-data effects. AICMC is found to be analogous to current mode co...

(for a buck converter, the inductor's DC current is equivalent to the converter's output current); allow the actual current-sense signal to pass unimpeded through the amplifier; and finally, dampen the high-frequency switching noise which is superimposed on the signal. The high ...
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...
