Estimating the term…
The present invention relates to a power factor correction circuit and a driving method thereof. The power factor correction circuit refers to an inductor receiving an input voltage and supplying output power, a power switch connected to the inductor and controlling an inductor current flowing in the inductor, and an auxiliary coil coupled with the inductor with a predetermined turn ratio. The power factor correction circuit controls the output power by controlling a switching operation of the power switch, and counts the number of times that the inductor current reaches a predetermined maximum current to turn off the power switch when the count result reaches a predetermined short circuit threshold count.
A power factor correction circuit comprising:
A driving method of a power factor correction circuit including an inductor receiving an input voltage and supplying output power, a power switch connected to the inductor to control an inductor current flowing in the inductor, and an auxiliary coil coupled with the inductor with a predetermined turn ratio, comprising:
