“…For PV charging stations connected to grid, the isolated configuration is the favorite one as it operates in high voltage levels and could provide a galvanic isolation between Alternative current part and direct current part of the system . [37], [38]. The key constrained point of the inverter design is the frequency stabilization.…”

Abstract.Within the next few years, Electrified vehicles are destined to become the essential component of the transport field. Consequently, the charging infrastructure should be developed in the same time. Among this substructure, Charging stations photovoltaic-assisted are attracting a substantial interest due to increased environmental awareness, cost reduction and rise in efficiency of the PV modules. The intention of this paper is to review the technological status of Photovoltaic-Electric vehicle (PV-EV) charging stations during the last decade. The PV-EV charging station is divided into two categories, which are PV-grid and PVstandalone charging systems. From a practical point view, the distinction between the two architectures is the bidirectional inverter, which is added to link the station to the smart grid. The technological infrastructure includes the common hardware components of every station, namely: PV array, dc-dc converter provided with MPPT control, energy storage unit, bidirectional dc charger and inverter. We investigate, compare and evaluate many valuable researches that contain the design and control of PV-EV charging system. Additionally, this concise overview reports the studies that include charging standards, the power converters topologies that focus on the adoption of Vehicle-to grid technology and the control for both PV-grid and PV standalone DC charging systems.

“…Central inverter configurations are the mainstream solution for large scale grid-tied PV plants (> 850 kW ) [4], due to its higher conversion efficiency (> 98% CEC) and lower cost per kW , compared to string, multi-string and microinverter configurations. Nevertheless, central inverter configurations show the lowest MPPT efficiency among all configurations, due to its single tracking system for the full PV plant [4].…”

Abstract-In most large-scale grid-tied photovoltaic (PV) plants, central inverter configurations are used, mainly due to higher converter efficiency and lower cost per kW . However, compared to other configurations, its Maximum Power Point Tracking (MPPT) efficiency is the lowest since it is the less distributed configuration. Under non-uniform conditions, as mismatch caused by aging and/or partial shading, several local maxima may arise in the PV curve, hence requiring additional actions to maximize the output power of the PV plant. Moreover, tighter grid codes have appeared, requiring for PV systems to limit power fluctuations. This paper presents an alternative to perform Global MPPT (GMPPT) while complying with stiffer grid code limitations. The proposed alternative adds an Energy Storage System (ESS) at inverter level, consisting of an ultracapacitor (UC) bank connected to the DC-link of a PV central inverter through interleaved DC-DC power converters. The proposed configuration is preliminary validated through simulations and tested under extreme conditions. The performance of the system is analyzed and compared to other existing solutions.

“…Nevertheless, the IFBB converters can perform voltage step-up and maintain continuous input current in a wide operation range. At the same time, a new quasi-Z-Source (qZS) DC-DC converter topology has emerged that has all the benefits of the IFBB topology and does not suffer from the high inrush current, has even higher step-up factor and therefore potentially wider operation range [6]- [8], [22], [23]. Therefore, the topologies with an input stage that can work as a current-source could be preferable in such low-voltage applications as power conditioners for photovoltaic panels and fuel-cells.…”

-This paper compares semiconductor losses of the galvanically isolated quasi-Z-source converter and full-bridge boost DC-DC converter with active clamping circuit. Operation principle of both converters is described. Short design guidelines are provided as well. Results of steady state analysis are used to calculate semiconductor power losses for both converters. Analytical expressions are derived for all types of semiconductor power losses present in these converters. The theoretical results were verified by means of numerical simulation performed in the PSIM simulation software. Its add-on module "Thermal module" was used to estimate semiconductor power losses using the datasheet parameters of the selected semiconductor devices. Results of calculations and simulation study were obtained for four operating points with different input voltage and constant input current to compare performance of the converters in renewable applications, like photovoltaic, where input voltage and power can vary significantly. Power loss breakdown is detailed and its dependence on the converter output power is analyzed. Recommendations are given for the use of the converter topologies in applications with low input voltage and relatively high input current.
