Premium Quality Silicon Controlled Rectifiers

Insulated Gate Bipolar Transistor (IGBT) Switch Mode Rectifiers Vs Silicon Controlled Rectifier (SCR) Thyristor Rectifiers


In applications such as electroplating, anodizing, colour anodizing, electroforming, electro-polishing, electrowinning, and hydrogen electrolysis, the choice of power source is critical for achieving high-quality results. Insulated Gate Bipolar Transistor (IGBT) switch mode rectifiers and Silicon-Controlled Rectifiers (SCR) thyristor rectifiers are two common options, each with their own advantages and limitations. Here are the benefits of IGBT and SCR rectifiers:


IGBT Switch Mode Rectifiers

High Efficiency:

It can convert AC to DC power with minimal power loss, leading to lower power consumption.

Rapid Response Time:

It responds quickly to changes, which are beneficial for processes requiring higher precision.

Precise Programming:

Automation is enhanced by the precise programming ability of the units, leading to improved process accuracy and consistency.

Compact and Low Maintenance:

These rectifiers are space-saving and have lower maintenance needs, reducing long-term costs.

Pulse Reverse Current (PRC) Rectifiers:

Pulse Reverse Current (PRC) Rectifiers are a specialized type of power electronics device used in various industrial applications, particularly in electroplating and electrowinning processes. IGBT rectifiers are suitable for periodic pulse reverse current rectifiers with features such as forward current adjustment, reverse current adjustment, dead band control, pulse adjustment, and frequency adjustment.

These rectifiers represent a sophisticated approach to power conversion in electrochemical processes, offering significant advantages over traditional DC rectifiers in terms of process control and product quality.


SCR Thyristor Rectifiers

High Reliability and Robustness:

Well-suited for harsh industrial environments, providing stable DC output.

Proven Performance:

Widely used in industry for decades, known for their durability.

Lower Efficiency:

It consumes more power because of linear voltage regulation, leading to higher operating costs.

Slower Response Time:

Less suitable for processes requiring rapid adjustments and high precision.


A Comparison

Precision and Efficiency:

For processes needing high precision and efficiency, IGBT switch mode rectifiers are preferred because of their superior accuracy, lower power consumption, and better automation capabilities. 

Robustness and Stability:

For environments demanding robustness and stable DC output, SCR thyristor rectifiers are more appropriate despite their lower efficiency. 

Digital automation enhances metal finishing by providing consistent output, reducing labor costs, and increasing efficiency.

IGBT switch mode rectifiers are particularly advantageous for automated processes due to their precise control and programming features.

Ultimately, the choice between IGBT and SCR rectifiers depends on the specific requirements and conditions of the metal finishing process.
