| Abstract: | The design of DC 220V power and its auxiliary power supply for a relay testing instrument are introduced. The design of multi-output transformer and reducing the common-mode interference is detail described. And a new isolation method is introduced for the transformer. The experimental results are given for verification the validity of the proposed design. |
