The Company That Started Solid State Induction
Pillar originated the solid state power supply for induction heating. That's not a marketing claim â it's the foundation our entire product line is built on. Decades of field-proven reliability, thousands of installations worldwide, and continuous refinement of IGBT, SCR, and MOSFET topologies mean you're specifying from the deepest bench of induction power expertise in the industry. Every converter we ship from Brookfield, Wisconsin reflects that history: purpose-built for induction, backed by engineers who understand your process, and supported with parts and field service for the full lifecycle of the equipment.
Three Proven Topologies â One Source
Different induction applications demand different switching technologies. Pillar manufactures all three major converter types in-house, so your power supply recommendation is driven by process requirements â not by a limited product catalog.
IGBT Converters
Insulated Gate Bipolar Transistor converters deliver high efficiency and precise control across a wide frequency range, ideal for demanding induction heating and melting applications requiring fast switching and responsive output regulation.
SCR Converters
Silicon Controlled Rectifier technology provides robust, time-tested performance for high-power applications. SCR converters excel in large-scale induction systems where rugged reliability and high current output are the primary requirements.
MOSFET Converters
Metal-Oxide-Semiconductor Field-Effect Transistor converters are optimized for high-frequency operation up to 450 kHz, making them the preferred choice for surface hardening, brazing, and precision induction processes requiring tight frequency control.
Power Supply Capabilities at a Glance
From compact 25 kW bench units to 18 MW industrial converters, Pillar's production lineup covers the full spectrum of induction power requirements.
High-Power SCR Systems
Output power up to 18 MW for large-scale induction melting, forging, and bulk heating. ISO 9001:2015 certified manufacturing from Brookfield, Wisconsin with full lifecycle parts and field service support.
IGBT Medium-Frequency Converters
Spanning a broad frequency range with precise output control, IGBT converters are engineered for through-heating, hardening, and process applications where efficiency and controllability are critical.
High-Frequency MOSFET Units
Operating up to 450 kHz for surface hardening, brazing, and precision induction tasks. Available as OEM replacements for Pillar, Westinghouse, and Cycle-Dyne induction systems.
