Commercial DC DC Converters Controlling the Track Circuit in Railway

The very first day when the Converters were introduced in the commercial domain, no one knew that these converters would have been so important that almost every activity- no matter big or small- would have been controlled by these small electronic devices. It would never be wrong to tell that these converters are being considered as the backbone of every commercial activity. These electronic devices have not only sped up the mobility of the locomotives but also enhanced the freight and passenger carrying capacity of the locomotives. The commercial DC DC converter in the form of important railway converters have spared the railways.

By this time, you would have got an idea that the railway locomotives use the power of the DC-DC converters to transform the AC overhead current to usable DC current by the help of pantograph and several powerful step-down transformers that use these converters as their essential part. But have you ever thought of the tracks on which the locomotives run? Have you ever wondered about the signalling system that makes the journey of the Train even at speed over 100 mph a safe one? All credits go to the railway DC DC converters. This is why the converters have been referred to as the lifeline of the railways.

In this section, let us focus on the track circuit of the railways. Yes, those tracks on which we can see a freight train to roll in order to move the goods from one place to another and the luxury trains moving the people from one destination to another. Even the tracks have the circuits that determine the part of the track that has been occupied by the train. It is not only that but the signalling system in railways is controlled by the circuit present on the track. The balise is the electronic device that is part of the automatic train protection signalling system.

Coming to the track circuit, it is helpful in determining the part of the track that has already been occupied by the trains. These converters are simple in design.

Functioning

In order to ensure a proper functioning of the track circuit, the tracks are divided into blocks. One unit track or block of the track is divided from the adjacent one with the help of the rails, which are insulated joints. These blocks or the units have signal system attached to monitor the movement of the train. These signals are transferred to the cabin of the locomotive. These signals are present next to the tracks except at the switches. Each unit of the track has the circuit that helps to determine whether the train is present or not.

In order to ensure that the entire system works properly in all weather, the waterproof DC DC converters have played a significant role. The importance of the DC-DC converters cannot be ignored as hardly any operations will remain functional without the aid of the commercial DC DC converter. The converters have made a significant contribution and the proof is just in front of all of us.
