Abstract
A converting device with PFC and dc/dc converting functions is provided. The converting device includes a power source providing a dc voltage, an inverter having an input terminal electrically connected to the power source and an output terminal, a transformer having a primary winding electrically connected to the output terminal of the inverter and a secondary winding, a rectifier/filter circuit having an input terminal electrically connected to the secondary winding of the transformer and an output terminal, and a PFC converter coupled to the output terminal of the rectifier/filter circuit and having an input terminal receiving an ac input voltage. The converting device converts the ac input voltage into an ac output voltage when the ac input voltage is normal, and converts the dc voltage to output the ac output voltage with the cooperation of the inverter, the transformer, the rectifier/filter circuit and the PFC converter when the ac input voltage is abnormal.
