Abstract

An adapter connection structure, which includes 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 the 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 reduces transmission loss.

Claims

1. An adapter device connection structure comprising

a first adapter device, connected to at least one input terminal to receive an input power, and converting said input power into a transitional power;

a second adapter device, connected to said first adapter device via a transit cable to receive said transitional power, converting said transitional power into a DC (Direct Current) output power, and outputting said DC output power from an output terminal; and

a DC power cable, connecting said second adapter device converter and said output terminal, and conducting said DC output power from said second adapter device converter to said output terminal;

wherein said first and second adapter devices are an AC/AC adapter and a AC/DC adapter, respectively, so as to reduce a power transmission loss in said transit cable.

2. The adapter connection structure according to claim 1, wherein said input terminal is installed in said first adapter device converter.

3. The adapter connection structure according to claim 1, wherein said input terminal is connected to said first adapter device via an AC (Alternating Current) power cable.

4. The adapter connection structure according to claim 1, wherein said transitional power has a peak voltage over 1.5 times higher than that of said DC output power.

5. The adapter connection structure according to claim 1, wherein at least one electromagnetic wave filter is arranged between said first adapter device and said input terminal, and between said second adapter device and said output terminal.

6. The adapter connection structure according to claim 5, wherein said electromagnetic wave filters are respectively integrated with said first adapter device and said second adapter device.

7. The adapter connection structure according to claim 1, wherein said second adapter device converter is connected to said output terminal via a DC power cable.

8. An adapter device connection structure comprising

a first adapter device, connected to at least one input terminal to receive an input power, and converting said input power into a transitional power;

a second adapter device, connected to said first adapter device via a transit cable to receive said transitional power, converting said transitional power into a DC (Direct Current) output power, and outputting said DC output power from an output terminal; and
