Abstract
According to one embodiment, a power convertor includes a buck-boost circuit; a switch driver, a switching controller, and a positive input terminal and a negative input terminal. In maximum power-point tracking, the switching controller causes the buck-boost circuit to stop outputting the output voltage, and varies the voltage value of the input voltage in a given range, which is from a lower-limit voltage value at which the switch driver is operable, by switching between the positive input terminal and the negative input terminal while varying a duty factor.
