    Abstract: The present invention discloses a parameter configuration method for elements of a PFC function converter. The converter has a PFC circuit modulating an input power into a DC modulated power and a transformer transforming the DC modulated power into an output power. The method of the present invention comprises a storage capacitor configuration procedure, a storage inductor configuration procedure and a verification procedure. The storage capacitor configuration procedure predetermines a test voltage and a rated bus voltage lower than the test voltage, determines a parameter of the storage capacitor according to the test voltage and uses the storage capacitor to supply the rated bus voltage. The storage inductor configuration procedure determines an inductance of a storage inductor to match the storage inductor and the primary coil of the transformer work in a discontinuous current mode. The verification procedure verifies whether the power factor of the converter exceeds 0.9.

    Abstract: The present invention discloses an adapter connection structure, which comprises a first converter and a second converter. The first converter is connected to at least one input terminal to receive an input power and converts the input power into a transitional power. The second converter is connected to the first converter via a transit cable to transmit the transitional power, converts the transitional power into a DC output power and outputs the DC output power via a DC power cable. As the transitional power transmitted from the first converter to the second converter is in form of a high-voltage and high-frequency AC power or a high-voltage DC power, the power transmission loss in the transit cable is reduced. Therefore, the present invention not only can reduce transmission loss but also can adopt a less expensive cable. Thus is reduced the total cost of buying and using the adapter.
