“…Controlling a larger number of phases can involve the use of specific control schemes. These control techniques should allow synchronization between phases in order to reduce the output voltage ripple and to distribute symmetrically the current between all phases [93] [94].…”

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.

“…In the conventional control method without current balancing, the switches of each phase share the same duty cycle, which may lead to unbalanced phase currents in real applications. In [17], the reason why voltage perturbations at the input can lead to significant equalising currents between phases was analysed. What is more, voltage disturbances at the input and the output of the converter can also lead to voltage differences between the converter phases and hence to unbalanced phase currents as in [18].…”

The dc/dc converter with interleaving and coupling technique is preferred in high-power applications for its excellent steady-state and transient-state performances. In this study, the principle of three-phase interleaved dc/dc converters with a coupled inductor is first analysed. Also, merits are proved theoretically based on the concepts of equivalent steady-state and transient-state inductance. As most of the proposed single-core coupled inductor may suffer several issues, such as asymmetrical coupling parameters, high manufacturing cost, and large dc flux, an equivalent model is then deduced to use twowingding coupled inductors instead of the single-core three-phase coupled inductor. With the proposed model, the manufacturing cost can be reduced, the parameters can be symmetrical and there will be nearly no dc flux. In real applications, however, the proposed model may also be faced with current unbalance among phases, which may lead to core saturation and even system failure. A phase-decoupled current sharing strategy is therefore proposed and used in the proposed topology. The superiority and practicability of proposed topology and current sharing method are verified by simulation in PSIM and prototype experiment results.

“…Their increased apparent switching frequency offers substantial voltage and significant reduce of the current ripple; hence, the size of their magnetic components is significantly reduced [1], [2]. However, on one hand, they suffer from increased number of active devices such as power switches, gate driver circuits, current sensing, and balanc-ing circuits [3]- [5]. On the other hand, the power consumption of the increased number of active devices penalizes their efficiency for lower power rates.…”
