Low Power IGBT & Mosfet Stacks

This brand offers mainly the MTL Series, a compact and ready-to-use Converter-Brake-Inverter power stack for motor control or inverter applications up to 20kW at 400V. Our customers generally use these stacks to research and develop new control strategies, nowadays several companies and universities are using our stacks around the world. Furthermore, also we offer Mosfets stacks and customized designs.

Medium Power IGBT Stacks

Our MTM series is the main range of standard product covering the medium power IGBT stacks assemblies offering a compact and very modular stacks from 30 to 300 kW using medium power range IGBT modules as industry's standard 34 and 62 mm modules and EconoDUAL™ or SimBus-F modules. Designed as three main blocks: rectifier block/DC-link/inverter to give an answer to the demand of this kind of power stack technologies. Any of these three blocks can be easily adapted to the application requirements. From this starting point, we can customize as per design in thight collaboration with our customers.

SCR & Diode Press-Pack Stacks


Thyristor and diode modular system with high reliability thanks to the construction with press-pack devices. Standard types available (and possibility of customizing), optimized and codified, natural or forced cooling, this series includes tested protection (thermal switch, ultrarapid fuses and RC network). You can get from this series a complete industrial rectifier, ready to use.

High Power IGBT Stacks

Highlights in our range of high power IGBTs stacks our MTH series which is designed for high power equipment , up to 700 kW. Topologies B6I B2I with IGBT modules and high power modules mainly PrimePACK ™ but also assemblies with Press- Pack IGBTs . In addition to our standard series of converters we can design, assemble and produce converters tailored to the needs of our client.

Press-Fit Diodes Stacks


Power stacks mounted with press-fit diodes, these diodes are directly fitted on aluminium plates.

Screw Type & Encapsulated Bridge Stacks


Power stacks mounted with screw type devices , available diodes and thyristors, allows the construction of cheap and robust rectifiers or power stacks mounted with multichip modules, habitually 1~ and 3~ bridge rectifiers, DIN rail series available.

Power Equipment


We have available a R+D team to to develop, design and produce custom cabinets. Furthermore, we have a standard wide range of power factor correction devices with resonance filter to improve the quality from your network and remove a possible reactive surcharge.

NeoGraf Solutions – Thermal interface pads

HITHERM™ HT-C3200 Thermal Interface Material (TIM) from NeoGraf is the first of its kind, compressible graphite sheet with thermal performance that matches traditional thermal grease without pump-out and dry-out failure modes.
