Switch mode technology versus SCR technology

When should you choose an SCR power supply over a switch mode power supply?

For over 35 years, plating electronic has been a trusted technology leader in DC and pulse reverse DC power supplies for electrochemical processes in industry and research. From electroplating and anodizing to Power-to-X applications and electrolysis, our mission has been to empower our customers with innovative, reliable power solutions tailored to their unique needs. With the launch of our SCR-based DC power supplies, we now offer an even broader range of options, ensuring the right technology for every application. 

Choosing between a switch mode power supply and an SCR power supply is not about which is better - it’s about understanding your specific requirements. Both technologies have distinct advantages that suit different operational environments. Here’s how to determine which is the best fit for your needs. 

Switch mode power supplies: Compact, efficient, and precise 

Switch mode power supplies are the cornerstone of modern DC power supply technology. They are ideal for applications where space, precision, and energy efficiency are critical. Key features include: 

  • High power density: 

    Delivering up to 240 kW DC power, switch mode power supplies feature a compact design with a small footprint (as little as 0.48 m²) made possible by advanced semiconductors and water cooling.

  • Low ripple: 

    With ripple values of less than 1%, switch mode power supplies are excellent for applications requiring stable, high-quality DC power.

  • Grid compatibility: 

    The integration of Active Front End (AFE) technology results in a total harmonic distortion for current (THDi) of less than 3%, ensuring compatibility with modern grids.

  • Energy efficiency: 

    Switch mode power supplies achieve efficiencies of up to 96%, making them a sustainable and cost-effective choice for many applications. 

When to choose a switch mode power supply:

Switch mode power supplies are perfect for industries where precision, efficiency, and space-saving designs are essential. They are particularly well-suited for applications like electroplating, printed circuit board production, and anodizing. 

SCR power supplies: Robust, reliable, and flexible 

SCR power supplies are the go-to solution for high-current, heavy-duty applications where reliability is paramount. Designed for demanding environments, they excel in industries requiring substantial power delivery with flexibility for unique operational conditions. Key features include: 

  • High power density for megawatt applications: 

    SCR power supplies are designed to handle applications like electrolysis, Power-to-X, and other high-current industrial processes requiring up to several megawatts of DC power.

  • Reliable performance under challenging grid conditions: 

    Even in environments with unstable or challenging grid conditions, SCR power supplies deliver consistent and reliable operation.

  • Application-specific flexibility: 

    SCR power supplies can be customized for specific needs, including grid connections, physical dimensions, or other requirements unique to your application.

  • Exceptional energy efficiency: 

    With overall efficiencies of up to 98%, SCR power supplies provide reliable performance while minimizing energy waste. 

When to choose an SCR power supply:

SCR power supplies are ideal for heavy-duty applications where high-current power, durability, and flexibility are essential. They are the preferred choice for industries like electrolysis, hydrogen production, anodizing, and arc furnaces.
