铁路运输
Railway is traditionally considered one of the best choices for both passenger and cargo transportation. Modern trains are often driven by electric locomotives.
DC traction motors are the most common drives used in electric trains. Traction substations are used to convert alternating current into direct current used in electric vehicles.
These substations receive energy from an external power supply system and distribute it between traction and non-traction consumers. A traction substation can provide electric power to electric trains, electric locomotives, trams, and trolleybuses.
Avalanche-type diodes are used in railway transport since they are the most stable and reliable in overload state. Such diodes are able to restore their parameters when the overload ends. These diodes can carry high loads due to their ability to dissipate a power pulse for a much longer period of time.

Auxiliary converters are another common application of power semiconductors in electric trains. This type of devices is designed to power auxiliary systems, control and lighting circuits, microclimate systems, battery charging, etc.
Power semiconductors have various designs. Proton-Electrotex makes semiconductor devices for electric trains in stud and disc housings.
Proton-Electrotex offers a wide range of customization options based on individual customer requirements to technical parameters, connections and appearance of devices. Please contact the sales department for more info or leave us your message online.
