Abstract A power factor calibrating method and device includes steps as to supply the rectified AC source to the load unit through DC convertor, to check the electricity consumping quantity of the load end by load detecting unit. When the consumption quantity is larger than the predetermined consumption rate the power factor calibrating control unit with start and instruct the convertor to carry out the power source factor calibration. The power factor calibrating device includes load detecting unit and a power factor control circuit which is connected with the convertor located between the rectifier and DC convertor and with a power factor calibrating control unit of one control convertor for carrying out the power factor calibration according to the consumption quantity of the electricity at the load end.
