Method for charging solar and wind energy battery

Abstract

The invention relates to a method for charging a solar and wind energy battery, which comprises an input rectification circuit, a transformation circuit, a control circuit and an output circuit and is characterized in that the control circuit (4) comprises a sampling unit, a comparing unit, a reference voltage generator and a pulse width modulation (PWM) unit, wherein a maximum power point tracking circuit (5) which modulates according to the output of a solar battery and a fan is arranged in the PWM unit. Compared with the prior charging method, the method also comprises the maximum operating power point tracking step by which a control signal is input to a PWM circuit so that the control circuit (4) can regulate an input voltage and an output voltage according to the characteristics of solar energy and wind energy; in addition, the method omits a transformer which is required in a traditional charging device, thus not only greatly improving the use effect of a solar and wind energy charging device but also providing technical support for the miniaturization of the solar and wind energy charging device and most efficiently utilizing the solar energy and the wind energy for charging.
