Abstract
A power control method of a power control device, includes: rectifying, by a rectifier, an input current of a system including the power control device; sensing, by a current sensor, a first current through a first switch and a second current through a second switch, wherein the first switch and the second switch are connected to an output of the rectifier; filtering the sensed first current and the sensed second current through a low pass filter; sampling, by a processor, the filtered first current and the filtered second current once per switching cycles of the first switch and the second switch; and performing balancing control based on the sampled first current and the sampled second current such that an average value of the first current through the first switch and the second current through the second switch is uniform or is substantially uniform for a period.
