Abstract: A joint structure of electronic element for linking circuit board and electronic element is provided. The joint structure of an electronic element for being electrically connected to a circuit board has at least one slot positioned thereon. And, the joint structure of the electronic element includes: at least one terminal which has a curved portion including a deflected angle with a normal line of a plane of the circuit board, wherein when the joint structure of the electronic element is connected with the slot, the terminal produces an elastic stress through suffering a jostle from the slot so as to urge against the slot for forming an electrical connection therebetween.

Abstract: The present invention relates to a power factor correction apparatus, which comprises: a rectifier device being inputted with one of a first amplitude AC voltage signal and a second amplitude AC voltage signal, wherein said first amplitude is higher than said second amplitude; a switch device for performing an on/off switching; a magnetic energy storing element electrically connected to said rectifier device and said switch device for converting an electric energy delivered by an electric level signal into a magnetic energy for storing when said switch device is switched on; and an electric charge storing element electrically connected to said magnetic energy storing element for receiving said magnetic energy stored in said magnetic energy storing element and storing as an electric energy when said switch device is switched off, which comprises two capacitors with a voltage endurance higher than said second amplitude and lower than/equal to said first amplitude, said two capacitors are series connected when s
