Maximum power point tracking (MPPT) for solar cells

The maximum power point tracking (MPPT) of solar cells is to ensure that the photovoltaic cell has the maximum output power to make full use of solar energy when the intensity of illumination changes. In general, the switching mode DC-DC converter is required to implement the MPPT function to maximize the output (output power) of the output voltage and the charging current,

The maximum power point tracking function of photovoltaic cells is realized by using switching, synchronous rectification and DC-DC conversion. The input voltage is up to 28V, which is very suitable for applications with large difference between input voltage and battery voltage.
