Phase-Shifting Rectifier Transformer:Principle and Application

06-05 2025 | By:

The phase-shifting rectifier transformer is a multi-phase rectifier power supply device specially used for medium and high voltage inverters. Its main features and uses are as follows:

phase-shifting rectifier transformer Features:
High mechanical strength and short-circuit bearing capacity: This transformer has high mechanical strength and can withstand short-circuit current to ensure safe and reliable operation.

Low noise and small size: The design focuses on reducing noise and reducing size, making installation easier and maintenance-free.

High insulation level and long life: High insulation material is used, and the partial discharge is small, thereby extending the service life of the product.

Resistant to moisture and thermal shock: It can work normally in humid environments and thermal shock conditions.

Multiple phase shifting methods: Common phase shifting methods include zigzag lines, hexagons, and extended triangles, which can effectively reduce harmonic pollution and improve power factor.

phase-shifting rectifier transformer Uses:

High-voltage variable frequency speed regulation: With the development of high-voltage frequency conversion technology, phase-shifting rectifier transformers have been widely used in the field of variable frequency speed regulation. It provides a stable multi-phase rectifier power supply for medium and high voltage inverters, thereby realizing efficient and energy-saving motor control.

Special industrial applications: Due to its high fire protection requirements and adaptability to large load fluctuations, phase-shifting rectifier transformers are widely used in special working environments such as offshore oil platforms, thermal power plants, water plants, metallurgy and chemical industry, mining and building materials.

Electrochemical industry: In the electrochemical industry, such as salt electrolysis and aluminum electrolysis, phase-shifting rectifier transformers meet different process requirements by adjusting the voltage regulation range (usually 55% to 105%).

Harmonic elimination in power systems: Phase-shifting rectifier transformers eliminate harmonic currents in the power grid and improve the overall performance of the system by changing the moment of the trigger pulse, that is, changing the size of the control angle α.

In summary, phase-shifting rectifier transformers not only have superior physical and electrical properties, but also play an important role in multiple industrial fields, especially in situations where efficient and stable power supply is required.
