Abstract: A power factor correction device, and a controller and a total harmonic distortion (THD) attenuator used by same. The power factor correction device comprises a converter and a controller (320) connected to the converter to obtain an input voltage. The controller (320) comprises a THD attenuator (407) for automatic THD optimization. The converter comprises an input current detection resistor (3R8), a power switch tube (3NMOS) and an output circuit. The input current detection resistor (3R8), the power switch tube (3NMOS) and the output circuit form a feedback control loop to maintain a constant output voltage. A THD optimization function is built in the device so that the entire device is capable of being accurately offset to a designed voltage so as to be used for THD optimization, thereby dispensing with external manual adjustment and overcoming internal technical deviations while achieving high consistency.
