“…The scientific literature proposes several active threephase rectifiers, which can be classified into (Fig. 8): Gridconnected rectifiers [82][83][84][85][86][87][88][89][90][91][92][93][94][95][96], Power Factor Corrector (PFC) [97][98][99][100][101][102][103][104][105][106][107] and Vienna rectifiers [108][109][110][111][112][113][114][115][116][117][118]. There is a large number of proposed converters, however, in order to reduce the number of studied converters, a parallel analysis of those topologies used by manufacturers has been made.…”

Emission of greenhouse gases and scarcity of fossil fuels have put the focus of the scientific community, industry and society on the electric vehicle (EV). In order to reduce CO 2 emissions, cuttingedge policies and regulations are being imposed worldwide, where the use of EVs is being encouraged. In the best of scenarios reaching 245 million EVs by 2030 is expected. Extensive use of EV-s requires the installation of a wide grid of charging stations and it is very important to stablish the best charging power topology in terms of efficiency and impact in the grid. This paper presents a review of the most relevant issues in EV charging station power topologies. This review includes the impact of the battery technology, currently existing standards and proposals for power converters in the charging stations. In this review process, some disadvantages of current chargers have been identified, such as poor efficiency and power factor. To solve these limitations, five unidirectional three-phase rectifier topologies have been proposed for fast EV charging stations that enhance the current situation of chargers. Simulation results show that all the proposed topologies improve the power factor issue without penalizing efficiency. The topologies with the best overall performance are the Vienna 6-switch and the Vienna T-type rectifier. These two converters achieve high efficiency and power factor, and they allow a better distribution of losses among semiconductors, which significantly increase the life-cycle of the semiconductor devices and the reliability of the converter.
