This review describes the driving system of the prototype solar car made by Korea National Transportation University to participate in the 2017 World Solar Challenge in Australia. Since it is a prototype vehicle for the purpose of participating in the competition, it was produced in accordance with the competition regulations. The solar car's drive system consists of a solar array to convert solar energy into electric energy, a maximum power point tracker (MPPT) controller to track the converted electric energy to maximum output, a battery to store the produced electric energy, A BLDC (Brushless DC) motor for driving the vehicle by converting energy into mechanical energy, and an engine controller for controlling the BLDC. Although it is not comparable to an electric vehicle (EV) commercialized as a vehicle for the purpose of participating in the WSC competition rather than a solar car intended for commercialization, it has been reviewed to help understand the basic concept of a solar car driving system.
