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.

Claims

1. An adapter connection structure comprising

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

a second converter, connected to said first converter 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 converter and said output terminal, and conducting said DC output power from said second converter to said output terminal.

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

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

4. The adapter connection structure according to claim 1, wherein said second converter is an AC/DC converter.

5. The adapter connection structure according to claim 4, wherein said first converter is an AC/AC converter.

6. The adapter connection structure according to claim 1, wherein said second converter is a DC/DC converter.

7. The adapter connection structure according to claim 6, wherein said first converter is an AC/DC converter, and said transitional power output by said AC/DC converter has a voltage higher than that of said DC output power.

8. 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.

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

10. The adapter connection structure according to claim 9, wherein said electromagnetic wave filters are respectively integrated with said first converter and said second converter.

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