ENVILINE™ TCR - Traction Controlled Rectifier

Maximizing the distance, balance and stability of the DC line

To power trains, metros and trams, it is necessary to use an electronic power converter (traction rectifier) to convert alternating current into direct current. The ENVILINE TCR (Traction Controlled Rectifier) is the right solution for maximizing the distance, balance and stability of the DC line. Additionally, the TCR can reduce losses in rolling stock and prevent interruptions caused by undervoltage.

We have more than 50 years of experience in design, construction and commissioning of rectifiers for traction and other industrial applications.

Type testing:
All rectifiers are compliant with EN 50328 and IEC 60146, and offer overload class according to these standards.

Cooling:
Natural cooling, or adaptive forced cooling, ensures low noise and practically maintenance free operation.

Protection philosophy:
TCRs are designed to provide overload current versus a specified time characteristic (thermal model of converter) and utilize an internal high speed current control loop to limit and stabilize the output current at pre-set time. Immediate overcurrent protection is established through blocking of the firing pulses, while fuses constitute protection against shorted thyristors and final protection against DC short circuit current. Each thyristor module is protected by an RC circuit. Two levels over temperature protection and many other protective options are available.
