What is a Phase-shifting Rectifier Transformer?

A phase-shifting rectifier transformer is a specially designed transformer used in inverter systems
to reduce harmonic distortion, improve power factor, and enhance the efficiency of rectification.
By introducing phase-shifted secondary windings, it enables multi-pulse rectification (such as 12-pulse, 24-pulse, or 36-pulse systems)
to meet the needs of modern power electronics applications.
