Abstract
A maximum power point detecting circuit is disclosed including: a power detector for generating a power detecting signal responsive to an output voltage and an output current of a solar cell; a comparator for comparing a previous power average value with a current power average value according to the power detecting signal for a constant time; and a discriminator for latching an output signal of the comparing means immediately after a current constant time, setting an output immediately before a previous constant time, and judging that an output power of the solar cell decreases when the current power average value is smaller than the previous power average value to generate a discriminating signal.
