Control Strategies for Bidirectional DC-DC Converters: An Overview

Family of multiport bidirectional DC-DC converters

Multiport DC–DC converters are of potential interest in applications such as generation systems utilising multiple sustainable energy sources. A family of multiport bidirectional DC–DC converters derived from a general topology is presented. The topology shows a combination of DC-link and magnetic coupling. This structure makes use of both methods to interconnect multiple sources without the pe...

Comparative Aspects in Control Strategies for Hybrid DC/DC Converters

Linear-switching hybrid DC/DC converters consist of a voltage linear regulator (classic NPN or nMOS topologies and LDO) connected in parallel with a switching DC/DC converter. In order to control these hybrid structures, different strategies exist, allowing to fix the switching frequency as a function of some parameters of the linear regulator. This article compares two control strategies that,...

Control of DC-DC Converters

A constant voltage regulator, to supply constant power loads, is realized using a Switched-capacitor converter. Exhaustive studies have been carried out to find the suitability of available control schemes and finally one control scheme investigated with (i) operation of the converter at different crossover frequencies (ii) operation of the converter at different phase Margins. Various operatin...

Overcurrent Protection in DC/DC Converters – An Overview

Fault protection is commonly available in most of power management chips to date and its accuracy highly praised, mainly in cases where driving rates reach a few Amperes, or even above. In this paper, some of most common techniques for overcurrent protection (OCP) applied to both switching and linear DC/DC supply voltages are revisited and their trade-offs analyzed. Current limitation approache...
