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.

HIRECT has developed specialized power electronic equipments for a range of applications. Thyristor control constant voltage and constant current power supply are used by R & D organizations like BARC, CAT, IPR etc. Constant Current Regulators are being supplied for Airport runway lighting. These are used for guidance during aircraft landing and take off at civil airports as well as air force stations. HIRECT systems are used for Naval frigates and submarines on high sea or patrol vessels on coast guard duty.

Starting with the supply of diodes for traction application, Hirect now caters to wide range of rectifiers for rolling stock application. High power electric locomotive, AC Electrical Multiple Units are powered by Hirect̢۪s on-board or under slung rectifiers. Hirect rectifiers are also installed on board Diesel locomotives and Diesel-Electric Multiple Units. Rectifiers for special purpose like OHE cars, Mobile Maintenance Units, Accidents Relief vans etc. are also catered. On-board Installation and Under-carriage slung version of rectifier sets are manufactured by highly trained work force and specially created infrastructure for a high degree of reliability in critical traction application.

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

The converter grade thyristor range extends upto 4350Amps with PIV upto 2800V incorporating standard packages of 14" unf stud in to hat range to 3"in capsule type. The inverter range is divided into two distinct types. One meant for standard low frequency inverter upto 4350 amps and 2800 volts and the other for high frequency applications such as induction heating and high frequency welding. The high frequency range has thyristors upto 1200 amps with voltages upto 2000 volts., 'turn off' times as low as 10 microsecs.
