Abstract
According to one embodiment, a power convertor includes a buck-boost circuit to be applied with an input voltage to convert the input voltage into an output voltage for output, the input voltage being generated by a power generation module that generates direct-current power; a switching controller that executes maximum power-point tracking to control power conversion of the buck-boost circuit such that the power generation module generates maximum direct-current power; and a mode controller that causes the switching controller to execute the maximum power-point tracking when an input current from the power generation module is larger than a preset current threshold, and when the input current is equal to or less than the current threshold, causes the switching controller to stop the maximum power-point tracking, and cause the buck-boost circuit to output the input voltage as the output voltage without the power conversion.
