The utility model provides a phase-shift rectification transformer. The transformer comprises an iron core, and a primary winding and a secondary winding which are wound on the iron core, wherein the secondary winding is arranged outside the primary winding; the inner layer of the primary winding is provided with a first electrostatic shield, and the outer layer of the primary winding is provided with a second electrostatic shield; the first electrostatic shield is connected with the start of the primary winding, and the second electrostatic shield is connected with the tail of the primary winding. The phase-shift rectification transformer provided by the utility model can inhibit overvoltage, so that the secondary winding of the phase-shift rectification transformer can supply power for multiple rectification hosts and power units, reliably and normally.
