| 摘要 |
The present invention relates to a novel structure of a transformer for a high-frequency switching-type direct-current (DC) rectifier, and particularly to an improved structure of a transformer applicable to a large-current low-voltage high-frequency switching-type rectifier, wherein the transformer is comprised of a ring-shaped iron core (made of materials such as dust core or nanometer crystalline silicon or amorphous silicone), which is provided with a primary side formed with winding(s) of copper wire(s), coupling with a secondary side that is formed with a newly-developed module or block, which replaces the secondary side that was constructed to provide output with copper wires or copper plate with wire wound thereon. A cooling water tube is arranged in the secondary-side module to remove heat with the water so as to maintain normal temperatures of the transformer in a pollution-free manner with reduced size and weight and easy assembling and reduced costs of the transformer.
