Semikron Power Modules: Welding and Induction Heating Solutions
Semikron has been a leading manufacturer of power modules for welding equipment and induction heating systems since 1951. The company’s comprehensive product portfolio, ranging from discrete power semiconductors to intelligent power modules, provides the high-frequency switching performance and reliability required for modern inverter welding machines and induction heating power supplies.
SKM Series IGBT Modules for Welding Inverters
The SKM series IGBT modules are specifically designed for welding power inverter applications. These modules provide the high-frequency switching capability essential for modern inverter welders, which operate at switching frequencies significantly higher than traditional transformer-based welding machines. The low-loss design improves welding power supply efficiency, reducing energy consumption and operating costs while maintaining stable arc characteristics.
SEMITOP Compact Modules for Induction Heating
The SEMITOP series features compact packaging optimized for welding and induction heating high-frequency applications. These modules combine multiple power switches in a space-efficient format, enabling the design of compact induction heating power supplies. The modules support the high-frequency switching required for induction heating processes including brazing, hardening, melting, and heat treatment across a wide range of industrial applications.
SKiiP Intelligent Power Modules
Semikron’s SKiiP intelligent power modules integrate driver and protection circuits directly with the power semiconductors, simplifying welding equipment design. The built-in driver eliminates the need for external gate drive circuitry, while integrated protection functions including over-temperature, over-current, and under-voltage lockout ensure reliable operation under the demanding conditions typical of industrial welding environments.
SK Series Thyristor and Diode Modules
For welding and heating applications requiring phase control or rectification, Semikron offers the SK series of thyristor and diode modules. Products such as the SK80DTA12 rectifier bridge module and SKKT107/16E thyristor module provide robust solutions for the input power stages of welding equipment. These modules use TO-240AA international standard packages and are available in various current and voltage ratings to match different welding power requirements.
Applications Across Welding and Heating Industries
Semikron power modules serve a broad spectrum of welding and induction heating applications. Inverter welders benefit from the high-frequency IGBT modules for precise arc control. Induction heating systems use the modules for frequency converter power supplies driving induction coils. Specific applications include induction brazing, induction hardening of automotive components, induction melting of metals, and industrial heat treatment processes. The modules’ ability to operate at high switching frequencies enables efficient power transfer to the workpiece while maintaining precise temperature control.
