A converting device with multiple input terminals and two output terminals is disclosed for converting Direct Current (DC) power from a power source to Alternating Current (AC) power. The converting device includes N pairs of input electrodes (N is an integer and N≧2), configured to receive the DC power from the power source, N maximum power point trackers, each coupled to one pair of the N pairs of input electrodes, configured to track a maximum power operation point for the DC power received from the one pair of the N pairs of input electrodes, two DC/DC converters, each coupled to one of the N maximum power point trackers, configured to convert a DC voltage received from the one of the N maximum power point trackers, a DC/AC inverter, coupled to the N DC/DC converters, configured to convert N DC voltages provided by the N DC/DC converters to an AC output signal, and a controller, coupled to the N DC/DC converters and the DC/AC inverter, configured to control the DC/DC conversion operation of the N DC/DC converters and the DC/AC conversion operation of the DC/AC inverter.
