Average current mode control of switching power supplies
TLDR
Average current mode control may be used effectively to control currents other than inductor current, allowing a much broader range of topological application.Abstract:
Current mode control as usually implemented in switching power supplies actually senses and controls peak inductor current. This gives rise to many serious problems, including poor noise immunity, a need for slope compensation, and peak-to-average current errors which the inherently low current loop gain cannot correct. Average current mode control eliminates these problems and may be used effectively to control currents other than inductor current, allowing a much broader range of topological application.read more

Predictive digital current programmed control
TL;DR: In this paper, the authors explored predictive digital current programmed control for three basic converters: buck, boost, and buck-boost, and found that for each variable of interest (valley, peak or average current) there is a choice of the appropriate pulse-width modulation method to achieve predictive current control without oscillation problems.

Design and Analysis of Novel Control Strategy for Battery and Supercapacitor Storage System
TL;DR: In this paper, a simple novel control strategy is designed and analyzed for a hybrid energy storage system (HESS), where batteries are used to balance the slow changing power surges, whereas super-capacitors (SC) are used by diverting the power surges to the SC system.

Topics in multiple-loop regulators and current-mode programming
TL;DR: In this article, a new circuit-oriented model of the current feedback path is derived which augments the well-known power stage canonical circuit model, and it is concluded that incorporation of a current-programmed power stage into a new power stage model is both justified and useful.
