Phase shift rectifier transformer is mainly composed of two modules: phase shifter and rectifier. The phase shifter usually adopts capacitor phase shifter circuit, which can adjust the phase of output voltage flexibly. The rectifier is responsible for converting high voltage alternating current to high voltage direct current, and its output voltage is directly affected by the phase shifter output voltage phase.

The basic principle of phase shifting
Phase shifting is to change the phase relationship of current or voltage through certain circuit design and control means. In a phase-shifted rectifier transformer, this is usually achieved through multiple windings of the transformer. The phase difference between the different windings can be precisely controlled to obtain the desired phase relationship at the output. The purpose of phase shift is to reduce harmonic interference and improve the quality and stability of DC output during rectification.
Realization of rectification process
Rectification is the process of converting alternating current into direct current. In a phase-shifting rectifier transformer, rectification is usually achieved by a bridge rectifier circuit. The circuit consists of multiple diodes or semiconductor devices such as thyristor, which can automatically switch the on-off state according to the phase relationship of the current, thus obtaining a smooth DC voltage at the output end. The key of the rectifier process is to control the turn-on and turn-off timing of semiconductor devices to ensure the efficiency of the rectifier and the stability of the output voltage.
Advantages of phase-shifting rectifier transformers
The phase shifting rectifier transformer combines the two technologies of phase shifting and rectification. It has many advantages. It can significantly improve the efficiency of rectification, reduce harmonic interference and improve the quality and stability of DC output. In addition, it also has the characteristics of compact structure, easy maintenance and long service life. Therefore, phase-shifting rectifier transformers have been widely used in the field of power electronics. Especially in the need of high-quality DC power supplies phase-shifting rectifier transformers play an important role.
