The three-phase first winding mentioned in this scheme is a winding with multi-stage taps. The joint of each tap is connected with the on-load voltage regulating switch which is controlled by a controller of the on-load voltage regulating switch, and the controller of the on-load voltage regulating switch is controlled by an input load voltage feedback signal. Each phase winding of the three-phase first winding with multi-stage taps is composed of nine sections and eleven joints, and each joints is connected with the on-load voltage regulating switch. The on-load voltage regulating switch has eight voltage regulating spans. In each span, the two joints of adjacent order numbers in each phase winding are communicated. So the higher the span is the less the coil of each winding is and the higher the secondary output voltage of the transformer is. Consequently, the output voltage can be regulated.
