Generalized small-signal modelling of dual active bridge DC/DC converter [PDF]

open access: yes, 2018
this paper presents a novel generalised approach of the small-signal modelling of dual active bridge (DAB) DC/DC converter. The adopted analysis is based on a per-unit fundamental frequency representation of the DAB. The outcome of the proposed modelling

Comparative Study of 4-Switch Buck-Boost Controller and Regular Buck-Boost

open access: yesInternational Journal on Advanced Science, Engineering and Information Technology, 2011
A very important characteristic that dc-dc converters require is the ability to efficiently regulate an output voltage with a wide ranging value of input voltages. A recently developed solution to this requirement is a synchronous 4-Switch Buck-Boost controller developed by Linear Technology. The Linear Technology’s LTC3780 controller chip enables  the

Microcontroller based bidirectional buck–boost converter for photo-voltaic power plant

open access: yesJournal of Electrical Systems and Information Technology, 2018
A common configuration for a stand-alone PV power system may consist of three converters: a buck converter for the PV panel to charge the battery, a boost converter for the battery to discharge to the load and one for the load voltage regulation.
