In this paper, the P&O algorithm in the technique of controlling maximum powerpoint trackers applied in inverters to obtain the maximum power generated from the solarsystem is presented. Solar panels have non-linear voltage and current characteristics that dependon temperature and irradiance reaching PV panels and PV arrays have a unique point of beingable to generate power maximum at each time point. The characteristics of solar radiationreaching the photovoltaic system are not stable at sunny times of the day, it is often changed byother factors such as partial cloud cover, total cloud cover or intensity, radiation varies by hour,by day and by season. As a result, the conversion of photovoltaic energy into electricity of PVpanels will be changed. The power generated by the PV system is unstable, leading to lowconversion efficiency. The application of algorithms in MPPT control technique to find thepoint that can generate the maximum power at any time in order to maximize the power receivedfrom the solar system. This paper will present simulation results to prove the correctness of theproposed method.Ô tô lai điện đang chứng tỏ được ưu điểm về tiết kiệm nhiên liệu và thân thiện vớimôi trường, để nâng cao ưu điểm này ô tô lai điện cần có một chiến lượt tối ưu hóa và quản lýnăng lượng hiệu quả.
