In order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. The Shore Power Supply which needs transferring 380V/50Hz to 450V/60Hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improving the environment. At the same time, in order to achieve better control, in this paper, sliding mode control is applied to the closed loop system. The structure of the main circuit, drive circuit and control system are described and the design of critical parameters are provided.

Journal of Electrical and Computer Engineering Innovations (JECEI) welcomes letters to the editor for the post-publication discussions and corrections which allows debate post publication on its site, through the Letters to Editor. Letters pertaining to manuscript published in JECEI should be sent to the editorial office of JECEI within three months of either online publication or before printed publication, except for critiques of original research. Following points are to be considering before sending the letters (comments) to the editor.

[1] Letters that include statements of statistics, facts, research, or theories should include appropriate references, although more than three are discouraged.

[2] Letters that are personal attacks on an author rather than thoughtful criticism of the author’s ideas will not be considered for publication.

[3] Letters can be no more than 300 words in length.

[4] Letter writers should include a statement at the beginning of the letter stating that it is being submitted either for publication or not.

[5] Anonymous letters will not be considered.

[6] Letter writers must include their city and state of residence or work.

[7] Letters will be edited for clarity and length.
