PROBLEM TO BE SOLVED: To provide a power-factor correction circuit function improving device for use in correcting and enhancing a power factor.SOLUTION: A power-factor correction circuit function improving device of the present invention includes a main load, a power-supply module, a power-factor correction module, a current-source module, and an auxiliary load. The power-supply module is used to rectify an AC voltage to a pulse DC voltage. The power-factor correction module is used to regulate the pulse DC voltage to a driving voltage. The current-source module is connected to the power-supply module, the main load, and one side of the power-factor correction module, and drives the main load by the driving voltage. The auxiliary load is connected to another one side of the power-factor correction module, and is driven by the power-factor correction module. |
