Abstract
This work is focused on a solar photovoltaics (PV)-based onboard charger using reconfigured motor windings. In the proposed scheme, the motor windings and traction converter switches form a three-phase interleaved buck converter (IBC). The IBC is interfaced with the solar PV and acts as the maximum power point tracking converter. The IBC reduces the current ripple at the battery side and improves the battery cycle life. Through IBC, a large amount of current at the battery side is paralleled in three inductors of the IBC, which reduces the on-state losses in the switches and copper loss in the inductors. Therefore, it is possible to increase the power level of the onboard charging system as high as that of the propulsion system with enhanced compactness of the system while reducing the cost. Moreover, the applied control strategy reduces the current sensor requirements in IBC and eliminates the proportional–integral controller, which is another major advantage of the proposed system compared to conventional control of the IBC. Furthermore, the switches are subjected to zero current switching. Finally, the real-time experiment of the proposed system was accomplished using the OPAL-RT platform for 6 kW of charging power.
期刊介绍:
The IEEE Journal of Photovoltaics is a peer-reviewed, archival publication reporting original and significant research results that advance the field of photovoltaics (PV). The PV field is diverse in its science base ranging from semiconductor and PV device physics to optics and the materials sciences. The journal publishes articles that connect this science base to PV science and technology. The intent is to publish original research results that are of primary interest to the photovoltaic specialist. The scope of the IEEE J. Photovoltaics incorporates: fundamentals and new concepts of PV conversion, including those based on nanostructured materials, low-dimensional physics, multiple charge generation, up/down converters, thermophotovoltaics, hot-carrier effects, plasmonics, metamorphic materials, luminescent concentrators, and rectennas; Si-based PV, including new cell designs, crystalline and non-crystalline Si, passivation, characterization and Si crystal growth; polycrystalline, amorphous and crystalline thin-film solar cell materials, including PV structures and solar cells based on II-VI, chalcopyrite, Si and other thin film absorbers; III-V PV materials, heterostructures, multijunction devices and concentrator PV; optics for light trapping, reflection control and concentration; organic PV including polymer, hybrid and dye sensitized solar cells; space PV including cell materials and PV devices, defects and reliability, environmental effects and protective materials; PV modeling and characterization methods; and other aspects of PV, including modules, power conditioning, inverters, balance-of-systems components, monitoring, analyses and simulations, and supporting PV module standards and measurements. Tutorial and review papers on these subjects are also published and occasionally special issues are published to treat particular areas in more depth and breadth.
