Converters & Inverters

With the Indian Railways introducing three phase drive systems in electric locomotives and electric multiple units, Hirect also joined hands with CLW to become a partner for the manufacture of static converter for locomotives with three phase drive systems. with the absorption of technology, Hirect has become an indigenoussource for auxiliary converter and other panels required in this locomotive. Hirect is the major supplier of 25kVA inverters for AC coaches. The under slung Inverters are built on Technical known-how from our collaborators. It offers unique features like Natural cooling. AC Coach Inverter 25kVA. To keep pace with new technology. Hirect has entered into foreign technical tie-up for static converter for replacement of rotary arno converters of Electric locomotives manufactured and operated by the Indian Railways, A large number of 180kVA converters have been manufactured and installed. Hirect also offers 3 x 100kVA converters for the three phase electric locomotives.

Power Modules

The modules package concept has now gained acceptance as it offers compact and easy to handle designs. The semiconductor junctions are electrically isolated from the base allowing common heatsinks and compact designs. The insulating materials used between chip and base is carefully chosen so that the impedance is minimised. The Hirect range extends upto 350 amps and 2200 volts and is available in Diode-Diode, Diode-Thyristor and Thyristor-Thyristor configurations
