A single-phase and three-phase combined in-phase power supply and transformation device comprises a single-phase traction transformer (TT), a three-phase YNd11 connecting compensation transformer (CPT) and a single-phase in-phase compensation device (CPD) thereof. The in-phase compensation device comprises an alternating current-direct current-alternating current converter. The traction transformer and the compensation transformer have equal effects to a three-phase and two-phase balance transformer with the phase of secondary side voltage being vertical. When in a normal state, the traction transformer, the compensation transformer and the in-phase compensation device thereof jointly supply power for a traction load by a specified proportion; when the compensation transformer or the in-phase compensation device quit the operation, the traction transformer can work independently for a short time; and a backup traction transformer (BTT) can replace the traction transformer to work and can ...
