Traction convertor
An IGBT-based propulsion converter that transforms catenary/transformer input into precisely regulated 3-phase output for traction motors.
Independent axle or bogie control; TCMS-ready (CAN/MVB).
IP54+ enclosures; under-frame, on-board, or machine-room mounting
Thermal Options: Liquid-cooled core; forced-air variants by application.
Auxillary convertor
IGBT-based auxiliary power unit that converts transformer/alternator/battery inputs into regulated three-phase AC and DC supplies for hotel loads (HVAC, lighting, compressors, pumps, control/battery charging).
AC inverter: Open-Loop V/f Control
Interfaces: RS485 / USB / CAN / MVB / WTB / MICAS; fibre-optic options
Mounting: Underframe, on-board, roof-mounted, or distributed modules
Vehicle Control Unit ( VCU )
The Vehicle Control Unit acts as the central intelligence of the propulsion system, coordinating traction, braking, and auxiliary operations. It manages real-time control logic, system interlocks, and communication with on-board subsystems through TCMS-compliant interfaces. Designed for reliability and safety, the VCU ensures optimized performance, fault handling, and seamless multiple-unit operation
HMI & Driver Display Unit
The Driver Display Unit provides the human–machine interface between the locomotive systems and the operator. It presents real-time operational data, alerts, and diagnostics in a clear and intuitive format. Integrated with the VCU, the DDU supports safe, informed, and efficient train operation under all conditions.
Remote Monitoring Systems (RMS)
The Locomotive Management Software (LMS) software provides integrated monitoring, control, diagnostics, event recording, fault management, and communication for propulsion, braking, auxiliary, and other locomotive subsystems through standard onboard communication networks. It supports real-time data acquisition, health monitoring, predictive maintenance, fault logging, operator interface functions, and interoperability with the Train Control and Management System (TCMS), enabling enhanced operational reliability, safety, maintainability, and lifecycle management while ensuring compliance with functional, cybersecurity, and software quality requirements for dependable operation on the Indian Railways network.
IGBT
Power IGBTs (Insulated Gate Bipolar Transistors ) are the heart of modern railway traction converters, enabling efficient control of electric locomotives, EMUs, and metro rolling stock
Distributed Power Wireless Control System (DPWCS)
The Distributed Power Wireless Control System (DPWCS) is a onboard system designed to enable synchronized remote control and monitoring of distributed locomotives in long-haul freight operations in accordance with applicable RDSO specifications and relevant international railway communication standards.
Loco Transformer
A 7775 kVA locomotive transformer is a high-capacity traction transformer used in electric locomotives to convert high-voltage power from the overhead supply into the required voltage levels for traction and auxiliary systems. It provides electrical isolation, efficient power distribution, and reliable operation under varying load conditions. Designed with robust insulation and cooling systems, it ensures high efficiency, durability, and dependable performance in demanding railway environments.
Traction Motor
The traction motors are three-phase squirrel-cage asynchronous machines fed through VVVF converters, delivering high starting torque, wide speed range, robust thermal performance, and reliable operation under varying adhesion conditions
