Abstract: A maximum power point tracking (MPPT) apparatus and a MPPT method are disclosed. A converter uses an inductor therein to perform power conversion operations according to a gating signal so as to convert an input electrical energy into an output electrical energy to a load. A controller monitors the voltage difference of the inductor and the element temperature, performs a lookup table operation or calculates the element characteristic according to the element temperature, and further uses the element characteristic and the voltage difference of the inductor for calculating a characteristic value and correspondingly adjusts the gating signal according to the characteristic value so as to track the power of the input electrical energy.
