Abstract
An interleaved power factor corrector includes a first PFC component, a second PFC component, a current sampling resistor, a current detection component, a voltage detection component, and a control component. The current detection component is configured to detect a current I, a current Iand a current Iin. The voltage detection component is configured to detect a voltage Uinputted into the interleaved power factor corrector and an output voltage U. The control component is configured to generate, according to the current I, current I, current Iin, voltage U, voltage Uand a preset target output voltage, a first PWM control signal and a second PWM control signal, in which the first PWM control signal is different from the second PWM control signal by a half of a carrier period. The interleaved power factor corrector has lower circuit cost.
