“…Higher switches frequencies can increase energy losses and noise. Thus, to increase the power density, reducing current ripple without increasing the switching frequency, multiphase bidirectional converter are used [88] [89] [90]. These converters are composed of a part that increases the voltage (boost mode) and another that reduces it (buck) [91].…”

Currently, many researchers from industry and academic institutions are working on the study of electric vehicles, battery systems and renewable energy sources (solar, wind, geothermal, etc.). In order to carry out research on each of these technologies it is required large capital investment for equipment. Additionally, problems must be faced such as variability of environmental parameters, large space requirements, pollution (in some cases), etc. The use of software and hardware to emulate different types of actual batteries shows to be a low-cost and environmentally friendly option due to some of its features. The battery emulator system has the ability to replicate the behavior of any kind of actual battery using a virtual battery model (also known as battery electric model) and a controllable DC/DC power converter to be used in laboratory environments. Moreover, emulators are not only used for batteries, these can be used to emulate fuel cells, photovoltaic systems, wind generators, thermoelectric generator, etc. This survey aims to present the technologies to implement battery emulators based on DC/DC power converters. This survey is split up into five sections. In the first section, as an introduction, we present the advantages offered by the use of battery emulators to the scientific community and the environment. The second section presents a review about batteries (technologies, models, model parameters, etc.) and also it includes the virtual battery models, which are the main components of battery emulators based on DC/DC power converters. In the third section, we present the main DC/DC power converter types used in these systems and their operation modes. Additionally, in section 4 are presented some case studies where different topologies battery emulators based on DC/DC power converters with battery model are analyzed. These topologies are focused on their use in electric vehicles (EV).Digital Object Identifier (DOI):http://dx. first section, as an introduction, we present the advantages offered by the use of battery emulators to the scientific community and the environment.

Interleaving switching techniques are well known and widely used for minimizing the output current ripples of one input source with several paralleled buck converters. For the case to minimize the output current ripples of different paralleled sources working with different dutycycles has never been taken into account. This paper proposes a new switching technique to minimize the output current ripples of multiple input sources paralleled with buck converters. The proposed switching technique is based on the peak-ripple cancellation with novel phase shift determination algorithm. The feasibility and the performance of the proposed switching technique are verified by simulation results and hardware implementation. The proposed switching technique can be used to harvest energy from PV. MPPT algorithm is also tested for the proposed technique, which would be used for integrating renewables into the smart grid.Index Terms--current ripple cancellation, multiple input, buck converters, MPPT, PV.

“…In consequence, interleaved architectures need a strict tracking of the inductor current. This current control is required to equilibrate the current among phases keeping the intrinsic benefits of interleaved architectures [2][3][4]. Some works using digital current-mode control are available in [15][16][17][18][19].…”

This paper is focused on the design of a test-bank to develop high-frequency digital control laws for Point-of-Load converters. As a result, a high-frequency digital DC/DC converter prototype has been completed using a Freescale's DSC as digital controller. During this exposition, we present the design guidelines to build this test-bank and how to adapt some state-ofthe-art digital control laws for DC/DC converters working at high switching frequencies. Experimental results validate these digital control laws and the global converter behavior
