This paper presents a buck–boost maximum power point tracking (MPPT) circuit suitable for solar cars. The MPPT controller, which consists of analog elements with a small number of complementary metal–oxide–semiconductor elements, achieved accurate tracking of the maximum power point of photovoltaic power generation and contributed to the power savings and weight reduction. A buck–boost dc–dc converter was adopted as the main power converter of the MPPT circuit to reduce the power-conversion loss due to the wide voltage change in the battery. The 12 proposed MPPT circuits were installed in a solar car called ‘2019 Tokai Challenger’ at an international convention and were shown to successfully generate sufficient solar power. © 2021 Institute of Electrical Engineers of Japan.
