Abstract：Serious unreasonable problems will be caused in using two ATSEs to complete three power supply switching,and the derived three CB ATSE also has the defect of power system power failure. Through technical analysis,this paper points out that the use of special three PC ATSE is the best scheme to correctly solve three power supply switching.
