a fast battery charger of solar vehicle with maximum power of solar cells based on sliding mode under

This paper proposed a control system for the battery charger of a solar vehicle. the battery charger has two parts, boost converter and isolated dc/ac/dc converter. the boost converter is controlled by a proposed control system based on sliding mode. in this controller, the mppt is implemented by an extreme point of the solar cell p-v curve. also, the control system of the dc/ac/dc converter is based on sliding mode with consideration of uncertainties of the output filter. a fast charging algorithm based on variable frequencies was carried out by the presented control system and charging of a lithium-ion battery was done during 20 min from soc 20% to soc 80%. the simulation results show control system effectiveness.
