Introduction

In the field of power electronics and electrical engineering, split-winding rectifier transformers play a pivotal role. They offer advantages in terms of versatility and efficiency, particularly in rectifying alternating current (AC) to direct current (DC). This article elucidates the working principle of these transformers, their applications, and the solutions provided by HOLEEP company.

Overview of Split-Winding Rectifier Transformers

A split-winding rectifier transformer is a type of transformer designed with primary and secondary windings that are split into multiple sections. This configuration facilitates rectification by allowing for different electrical outputs and helps in reducing harmonics in power systems.

Working Principle

The split-winding rectifier transformer operates by dividing its secondary winding into equal parts. This division aids in supplying the required voltage levels and current paths for rectification purposes. The principle involves:

• Magnetic coupling of primary and secondary windings.
• Utilization of a center-tapped secondary winding for efficient rectification.
• Reduction of harmonic currents using split winding configurations.

Applications

These transformers are widely used in industrial applications that require robust and reliable power supply systems. Some of the key applications include:

• Rectifiers for industrial DC motors.
• Uninterruptible power supplies (UPS).
• Electrochemical processes such as electrolysis and electroplating.

Numerical Analysis and Parameters

Split-winding rectifier transformers are characterized by the following parameters:

• Voltage Rating: Typically ranges from 1 kV to 35 kV.
• Current Rating: Can exceed 2000 A in heavy industrial settings.
• Frequency: Commonly designed for 50/60 Hz systems.
• Efficiency: Generally exceeds 95% under optimal load conditions.
• Harmonic Reduction: Employs a design that significantly lowers THD (Total Harmonic Distortion).
