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.</span></span></span> Solar Vehicle, MPPT, Isolated DC/AC/DC Converter Sliding Mode Control, Uncertainties of the Filter. 1 11 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-2066-4&slc_lang=en&sid=1 Abolfazl Masnabadi abolfazlmasnabadi73@gmail.com 1800319475328460014017 1800319475328460014017 No Arak University of Thechnology Mehdi Asadi m.asadi@arakut.ac.ir 1800319475328460014018 0000000173421584 Yes Arak University of Technology
