Ridley current mode
WebJan 20, 2015 · A current-mode-controlled regulator differs from a voltage-mode equivalent by the addition of a second loop feeding back the inductor current which then contributes to the derivation of the PWM ramp. This feedback signal comprises two parts: the AC ripple current, and the DC or average value of the inductor current. Webcurrent-mode control - only that both topologies are viable choices in today’s environment. There are considerations which could point to one or the other as more optimum for each particular application. Some of these are outlined below: Consider the use of current-mode if: 1. The power supply output is to be a current source or very high ...

WebR. Ridley Published 2000 Engineering For working power supply engineers, the Unitrode handbook is often the standard reference for control analysis. This paper gives a very simple extension to the existing Unitrode models that accounts for the subharmonic oscillation phenomenon seen in current-mode controlled converters. WebModel, proposed by V. Vorperian [1] and the small-signal model for peak current-mode control, by Raymond B. Ridley [2] are displayed in Figure 3. The equations derived according to the model will be applied in compensation design for peak current-mode buck converters. Figure 3. The Buck PWM switch model and the small-signal model for peak ...
