IGBT Inverter
Ignite Inverter


These compactly built power supplies adopt digitally controlled based IGBT Inverter design and are available at power ratings from 25 KW to 1500 KW and frequency range of 500 Hz to 10000 Hz. A near-unity high power factor of (>0.98) is achieved throughout the melt cycle. Field reports indicate a reduction in energy consumption of up to 3 % due IGBT based design. The system provides 100% isolation from input power in case of a short circuit at the output. Modular design facilitates easier maintenance and component replacements. An optional touch screen HMI-based front control panel is provided for easier access and view.

We convey our sincere thanks and our appreciation to M/ s Electrotherm family for the development, realization, testing, qualification and commissioning of 10 MW power supply system for our Plasma Wind Tunnel facility. We are extremely glad that M/ s Electrotherm has taken up this challenging task, when no such system was existing in the country. We wish, we should have many more such collaborative ventures in future with M/ s Electrotherm and contribute to ISRO's futuristic advanced R&D programmes.
Mr. P.A. Krishnamoorthy, VSSC-ISRO
Hereby we feel glad to have 4000 KW/ 10 Ton DTi Furnace set along with HSMC lX Caster. We have commissioned this equipments in our plant on 21st May 2018 & found performance which was committed by Electrotherm was achieved. Electrotherm's project execution was extraordinary & their process understanding & support was remarkable. Looking to the performance of other equipments of other makes running within our group, we have found performance of Electrotherm make DTi Furnace to be best.
