Abstract:
A standalone solar energy conversion system includes a first DC-DC conversion apparatus, a second DC-DC conversion apparatus, and a control apparatus. The first DC-DC conversion apparatus receives a DC voltage and converts a voltage level of the DC voltage to provide a capacitance voltage. The second DC-DC conversion apparatus receives the capacitance voltage and converts a voltage level of the capacitance voltage. The control apparatus includes a first comparison unit and a second comparison unit. The capacitance voltage is compared to a first capacitance voltage command and a second capacitance voltage command through the first comparison unit and the second comparison unit, respectively, thus controlling output powers of the first DC-DC conversion apparatus and the second DC-DC conversion apparatus.
