An alternating-direct current conversion device and a power factor correction method therefor. The alternating-direct current conversion device contains a rectification circuit (10) and an active power factor correction circuit (20). The rectification circuit is electrically connected to a power supply (100) and used to convert an alternating current into a direct current, and has a positive electrode output end (12) and a negative electrode output end (14) for outputting the direct current. One side of the active power factor correction circuit is electrically connected to the rectification circuit, and the other side thereof is electrically connected to a load (200), which is used to suppress the voltage ripple output to the load. |
