MPPT SOLAR CHARGER


DC boost converter designed to maximize the power generated by photovoltaic panels independent of temperature and amount of solar radiation. The optimization of the power conversion is obtained with embedded logic which performs the MPPT (max power point tracking) algorithm on the PV cells connected to the converter. It works at a fixed frequency in PWM mode, where the duty cycle is controlled by the embedded logic running a “perturb & observe” MPPT algorithm. Safety of the application is guaranteed by stopping the drivers in case of output over voltage or over temperature.
